Given f(2) = 12, which of the following could be an equation of the function?
a. f(x) = 8x – 2
b. f(x) = 4x + 4
c. f(x) = 6x – 4
d. f(x) = –4x – 4

Step-by-step explanation:

We are given that:

f(2)=12

We have to determine which could be the equation of the function.

i.e. the function which satisfies f(2)=12

A. f(x) = 8x – 2

f(2)=8×2-2

f(2)=14

B. f(x) = 4x + 4

f(2)=4×2+4

f(2)=12

C. f(x) = 6x – 4

f(2)=6×2-4

f(2)=8

D. f(x) = –4x – 4

f(2)= -4×2-4

f(2)= -12

Hence, given f(2) = 12, equation of the function could be:

B. f(x) = 4x + 4

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
