Question

Can someone who's really good at math help me with this?

for f(x) evaluate each of the following:
a. f(0)
b. f(6)
show all your work

Answer 1

Explanation:

a)

f(0) is just the function f(x) evaluated at 0, meaning we need to plug in 0 to the function.

What piece of this function should we plug 0 in? Well, because 0 is less than 5, plug it into the first piece.

so f(0) = 0 + 4 = 5

b)

By similar reasoning:

f(6) = 8

because 5 <= 6 < 7
