Find f(4). Put your final answer in function form! f(x)=3x+5 g(x) = 2x^2-4 h(x) = -3x-9

Step-by-step explanation:

Given function f(x), when you want to find f(4) you just put 4 for every x in the equation of the function.

f(x) = 3x + 5    ⇒    f(4) = 3(4) + 5 = 12 + 5 = 17

g(x) = 2x² - 4   ⇒    g(4) = 2(4)² - 4 = 2•16 - 4 = 32 - 4 = 28

h(x) = -3x - 9   ⇒    h(4) = -3(4) - 9 = -12 - 9 = -21

1/8 3/16 3/4

you put them as all the same denominator and multiply
