Pls help me with this question! Pls show work if you can if not the it’s totally fine! Thank you! (10 points)

Answer 1

A is = 0

B is = 0

C is = 14

Explanation:

in the function, f(x) = 2x + 8,

the values in column x, is replace with the numbers, e.g if x is -4, then puting the value -4 in the equation, we obtain, f(x) = 2(-4) + 8 = 0.

in cases of column f(x), replace it with the given value, e.g if f(x) is 8, then 8 = 2(x) + 8, then the value of x is 0

Answer 3

see explanation

Explanation:

Given

f(x) = 2x + 8

When x = - 4 then

f(- 4) = 2(- 4) + 8 = - 8 + 8 = 0 ⇒ A = 0

When f(x) = 8, then

2x + 8 = 8 ( subtract 8 from both sides )

2x = 0 ⇒ x = 0 ⇒ B = 0

When x = 3, then

f(3) = 2(3) + 8 = 6 + 8 = 14 ⇒ C = 14

x f(x)

- 4 0

0 8
