Question

(I jut this in word form so someone would understand better but can someone please try helping me solve this. I only need help with this 1 problem.)

Evaluate this pricewise function at x=-4 and x=4.
f(x)={x^2, if x less than or equal to -4
{x^3, if -4 less than x less than or equal to1
{square root x, if x greater than 1

Answer 1

f(x)={x^2, if x ≤ -4
{x^3, if -4 < x ≤ 1
{√x, if x > 1

so if x = -4, it belongs to the first function
f(-4) = (-4)^2 = 16

if x = 4, we have the last function
f(4) = √4 = 2

Answer 2

Oh my god!! THANK YOU JESUS!! I have spend a whole day trying to find someone to help me. Thank you so much Reiny!!!
