Question

Find f(10) for this piecewise-defined function.

f(x) = { -4x + 1 if x < 3
{2/5x -3 if x > 3


Write your answer as an integer or as a fraction in simplest form.
f(10) =

Answer 1

-39

Explanation:

I cannot provide picture, but plug 10 in for x for both equations

-4(10)+1 = -39 -39 less than 3? yes

2/5(10)-3 = 1 1 is greater than or equal to 3? no

the value of y when f(10) is -39

since when you plug 10 in for x -39 is the result
