Question

Can someone help please?

Answer 1

Answer:

  g(7) = 16

Step-by-step explanation:

When evaluating piecewise-defined functions, the first step is to determine which domain the value of the independent variable falls into. Then the associated function is evaluated in the usual way.

__

For x=7, the applicable domain is (2, ∞). This means the applicable function is ...

  g(x) = (x +1)(x -5)

For x=7, this is ...

  g(7) = (7 +1)(7 -5) = (8)(2)

  g(7) = 16
