Explanation:
The minimum number of points needed to draw a strait line graph is 2. However, 3 is better as one of them forms a check. They should all line up. If not then something is wrong.
Lets determine 2 points
The line will 'cross' the y axis at
x
=
0
and cross the x axis at
y
=
0
So we can determine these points (intercepts) by substitution.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For y-intercept set
x
=
0
giving:
y
=
2
x
.
.
+
2
y
=

×
0
)
+
2
→
y
=
2
So y-intercept is at the point
(
x
,
y
)
=
(
0
,
2
)
For x-intercept set
y
=
0
giving:
0
=
2
x
+
2
Subtract
2
from both sides
0

=

x

=

x
+

Divide both sides by

But

and

=

So the y-intercept is at the point
(
x

y
)
=
(

)
Answer: A. 45 must be sold to make a profit of $90
(-2,2)(2,-2)
slope = (-2 - 2) / (2 - (-2) = -4/4 = -1
as far as point slope form, there can be 2 answers...
y - y1 = m(x - x1)
slope(m) = -1
using points (-2,2)...x1 = -2 and y1 = 2
now we sub
y - 2 = -1(x - (-2) =
y - 2 = -1(x + 2) <== or could be written as y - 2 = - (x + 2)
y - y1 = m(x - x1)
slope(m) = -1
using points (2,-2)...x1 = 2 and y1 = -2
now we sub
y - (-2) = -1(x - 2) =
y + 2 = -1(x - 2) <== or can be written as y + 2 = - (x - 2)
either one of those answers is ur point slope form
Answer:
The parameters in the parent function are:
- the parameter correspondig to - 3 in the given function is 0 in the parent function.
- the parameter corresponding to 1/2 in the given function is 1 in the parent function, and
- the parameter corresponding to - 1 in the given function is 1 in the parent function.
Explanation:
The given function is 
.
The parent function of 
. The parameters of the given function are -1 (which is mutlyplying the value of cosine, 1/2 which is multiplying the argument (x), and - 3 which is subtracted.
In the parent function, those values are 1, 1, and 0.
It may help you representing the parameters in the given function with letters:
Then, in the given function A = - 1, B = 1/2, and C = -3.
Now, you can write the parent function:
Then, the parameters are A = - 1, B = 1, and C = 0.
