Read each question carefully and evaluate the given functions for the specified input values. Show your work where indicated.

Evaluate each function for the given value.

1. If f(x) = x + 7, then f(3) =

2. If g(x) = 2x - 5, then g(4) =

3. If h(x) = x² + 1, then h(-2) =

Evaluate the following functions. Show all your steps.

1. Given f(x) = 3x + 10, find f(-5).

2. Given g(x) = x² - 3x + 2, find g(0).
