If f(x) = -2x + 8, and f(k) = -10, what is the value
of k? step by step please

Hello there!

We are given the function:

We want to find the value of k. First, we know that f(k) is -10. We substitute x = k and f(x) = -10.

Solving the equation. First, we subtract both sides by 8.

Divide both sides by -2.

Therefore, k = 9

When we substitute k = 9 in f(k), the value is -10.

Let me know if you have any questions!

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
