I would like to know how find the solution to these functions

Question

For the functions g(x) = 3x +2

Evaluate g(6) * g(9)

Evaluate g(6) - g(6)

Let f(x) = x² - 2x

Evaluate 3 * f(-5)

Evaluate f(3) + f(2)

Answer 1

Okay, well these problems are fairly straightforward.

g(6) * g(9) = (3(6) + 2) * (3(9)+ 2) = (20) * (29) = 5,800

g(6) - g(6) = 0, maybe you typed it wrong but this apparently cancels itself out

Same with the f(x) function

3 * f(-5) = 3 * (-5)^2 - 2(-5) = 3 * ((25)-(-10)) = 3 * (35) = 105

f(3) + f(2) = ((3)^2 - 2(3)) + ((2)^2 - 2*(2)) = (3) + (0) = 3
