The image contains a series of math problems involving functions. I'll break these into manageable sections, solve them, and explain each step clearly.

Let’s address a few at a time. If you have specific numbers you want prioritized, let me know!

Problem 1:

g(x) = -7x; x = 4 Substitute $x = 4$ into $g(x)$: $g(x) = -7(4) = -28$

Problem 2:

f(x) = -2x; x = -6 Substitute $x = -6$ into $f(x)$: $f(x) = -2(-6) = 12$

Problem 3:

k(x) = 3x - 11; x = -12 Substitute $x = -12$ into $k(x)$: $k(x) = 3(-12) - 11 = -36 - 11 = -47$

Problem 4:

t(x) = 9x + 10; x = -1 Substitute $x = -1$ into $t(x)$: $t(x) = 9(-1) + 10 = -9 + 10 = 1$

Would you like me to continue solving the rest? Let me know!
