I need help on number 2

Nina [5.8K]

9514 1404 393

Answer:

a. 405

b. -2

c. 5

d. 43

Step-by-step explanation:

I don't like doing arithmetic any more than you do, so I let a calculator do it for me. A spreadsheet works well for this, too. The function values are shown in the attachment.

Put the function argument where the variable is and do the arithmetic.

a. h(4) = 5·3^4 = 405

b. d(2) = 7 -9(2 -1) = -2

c. h(0) = 5·3^0 = 5

d. d(-3) = 7 -9(-3 -1) = 43
