Is relation t a function? Is the inverse of relations t a function? Relation t

seraphim [82]

Relation t is a function because it has no repeating x values

the inverse of relation t is when u switch the x and y values.
ex. inverse of (0,-2) is (-2,0).

and yes, the inverse of relation t is also a function because there are no repeating x values.

The campers in cabin b walked 2/3 of the way to silver stream. how many miles did they walk

jasenka [17]

2/3 of 8 miles is 5 and 1/3 miles. So they walked about 5 and 1/3 miles there.

Raoul saves $14.50 each month for 3 months. He puts his money in the bank and earns $0.33 interest . Hector puts \$3.60 e each w

Norma-Jean [14]

Answer:

$0.63

Step-by-step explanation:

Raoul saves $14.50 each month for 3 months. Total amount saved is 14.50 * 3 = $43.50

He earned an interest of $0.33.

The total amount of money he has is thus: 43.50 + 0.33 = $43.83

Hector puts $3.60 each week for 12 weeks. Total amount save by Hector is thus 3.60 * 12 = $43.2

Now we are asked to get how much money Raoul has. To get this, we simply subtract the amount of money Hector has from that of Raoul

That would be 43.83 - 43.2 = $0.63

Find VA
simplify fraction
set deonmenator equal to zero
that value is VA
cannot cross VA

fidn HA
if the degree of the numerator is less than the degree of the denomenator, then the HA is y=0
if the degree is equal, then divide he leading coeficient of the numerator by the leading coeficient of the deonmenator

to find if the fn crosses the HA, set the HA equaal to the reduced fn and solve, if you get a false statement, then it does not cross

holes are found by where if you have the numberator and deonmentoar are the same degree and they have a factor of same multiplicity example
f(x)= $\frac{(x+2)(x-3)}{(x-3)(x-5)}$
there is a hole at x=3 and to find the y coordinate, subsitute x=3 into reduced fraction

so

14.
make one fraction
f(x)=(2x-1)/(x-1)
x and y intercept
xint is f(x)=0
xintercept= 1/2 (1/2,0)
y intercept is when x=0 so set x=0
-1/-1=1
yintercept is y=1 aka (0,1)

VA set denom to zeero
x-1=0
x=1
VA at x=1

HA degree is same so divide leading coefs
2/1=2
HA at y=2

crosses HA?
2=(2x-1)/(x-1)
2x-1=x-1
x-1=-1
x=0
crosses ha at x=0 and
f(x)=(2(0)-1)/(0-1)=-1/-1=1
crosses HA at (0,1)

no holes

find where the fn is negative and positive
(2x-1) is zero at x=1/2
x-1 is zero at x=1
so in between, those, (1/2 and 1), the graph is negative (positive/negative=negative)
outside of that interval, the graph is positive (positive/positive=positive, negative/negative=negative) so graph is drawn on attachment

15. factor
f(x)=(x-2)/[(x-4)(x+1)]
VA set denom to zero
x-4=0
x+1=0
VAs at x=4 and -1

HA
degree of numberateor is smaller to HA is y=0

crosses HA?
0=(x-2)/(x^2-3x-4)
0=x-2
2=x
yes, at (2,0)

holes? no

find positive and negative

graph included

16.
VA=x is x=1
x=1
x-1=0
reduced denom is (x-1)
HA is y=2
degrees are same
2/1=2
(2x+something)/(x-1)
xint at -4,=
deonm when set to zero, etuals -4
2x+something=0 yeilds x=-4 so
2(-4)+something=0
-8+something=0
something=8

(2x+8)/(x-1)

hole at (6,4)
factored out bit is x=6
x=6
x-6=0

multiply whole equation by (x-6)/(x-6)

the function is
f(x)= $\frac{(2x+8)(x-6)}{(x-1)(x-6)}$ aka
f(x)= $\frac{2x^2-4x-48}{x^2-7x+6}$

17.
factor
f(x)= $\frac{(x+1)(x+5)}{(x-2)(x+5)}$
x+5=0
x=-5
hole at x=-5
sub into reduced fn (f(x)= $\frac{x+1}{x-2}$ )
4/7
hole at (-5,4/7)

degree is same so divide leading coeficients
1/1=1
HA=1

VA is set reduced denom to zero
(x-2) is reduced
x-2=0
x=2
VA is at x=2
