Answer: -1
Step-by-step explanation: f(x) is another way of saying y. So when y is 3, according to the table, x is -1
Answer:
see explanation
Step-by-step explanation:
5x² + 5x + 3 = 0 ← in standard form
with a = 5 , b = 5 , c = 3
Solve using the quadratic formula
x =

Answer:

Step-by-step explanation:
Given

Required
Determine the inverse function
Start by replacing f(x) with y

Swap the positions of y and x

Make y the subject: <em>Add 4 to both sides</em>


Make y the subject: <em>Divide through by 2</em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
Replace y with f-1(x)

Answer:
I think the answer is A.Negative
Step-by-step explanation:
From x=-5 to x=0 the slope is decreasing and from x=1 to x=6 it keeps decreasing.
Answer:
a) Q(-2,1) is false
b) Q(-5,2) is false
c)Q(3,8) is true
d)Q(9,10) is true
Step-by-step explanation:
Given data is
is predicate that
then
. where
are rational numbers.
a)
when 
Here
that is
satisfied. Then

this is wrong. since 
That is 
Thus
is false.
b)
Assume
.
That is 
Here
that is
this condition is satisfied.
Then

this is not true. since
.
This is similar to the truth value of part (a).
Since in both
satisfied and
for both the points.
c)
if
that is
and
Here
this satisfies the condition
.
Then 
This also satisfies the condition
.
Hence
exists and it is true.
d)
Assume 
Here
satisfies the condition 
Then 
satisfies the condition
.
Thus,
point exists and it is true. This satisfies the same values as in part (c)
