Question

F(x) = x + 2, 2 < 0
f (x) = 4x, x > 0
what is f(-3)

Answer 1

The zero of a function is the x-value that, when plugged into a function, makes the function equal to 0. f(x) means that we have a function of x. The zero of the function f(x)=2x-2 is the x-value that makes f(x) = 0. So we can just set the function equal to 0, and then solve for x!
