The value of r(x) at f(- 6) = 8.
We have the function r(x) =
We have to find the value of r(x) at x = - 6.
<h3>If f(x) = 5x + 3, then find the value of f(-2).</h3>
Substitute x = - 2 in the value of f(x) -
f(-2) = 5 (-2) + 3 = - 10 + 3 = - 7.
According to question, we have -
f(x) =
Substitute r = -6 in f(x), we have -
f(-6) =
f(-6) = - 2 x - 2 + 4
f(-6) = 4 + 4 = 8
Hence, the value of f(x) at f(- 6) = 8.

Answer:
(2, -3)
Step-by-step explanation:
The rule is every number x2 plus 5
Answer:
B
Step-by-step explanation:
First a linear function has no variables to a power other than 1
That means we can eliminate answers A ,C D and E
Looking at B
y + 7 = 5x
Subtract 7 from each side
y+7-7 = 5x -7
y = 5x-7
This is in the form of a line (y=mx+b)
This is linear
