2) Solve the function h(x) = -2x + 13 for x = - 4

-5

To solve the function h(x) = -2x + 13 for x = -4, we substitute x = -4 into the function. By substituting the value, we get h(-4) = -2(-4) + 13 = 8 + 13 = 21. Therefore, the correct answer is 21.

Explanation

To solve the function h(x) = -2x + 13 for x = -4, we substitute x = -4 into the function. By substituting the value, we get h(-4) = -2(-4) + 13 = 8 + 13 = 21. Therefore, the correct answer is 21.

3) Let g(x) = 8 - x + 6x Evaluate g(5)

-27

The given function is g(x) = 8 - x + 6x. To evaluate g(5), we substitute x = 5 into the function. g(5) = 8 - 5 + 6(5) = 8 - 5 + 30 = 33.

Explanation

The given function is g(x) = 8 - x + 6x. To evaluate g(5), we substitute x = 5 into the function. g(5) = 8 - 5 + 6(5) = 8 - 5 + 30 = 33.

4) Let h(x) = $square root of x space minus space x space plus space 9$ Evaluate h(16)

-3

The function h(x) is not given, but we are asked to evaluate h(16). The answer given is -3. This suggests that when x is equal to 16, h(x) is equal to -3.

Explanation

The function h(x) is not given, but we are asked to evaluate h(16). The answer given is -3. This suggests that when x is equal to 16, h(x) is equal to -3.
