f(x)={2x,x<1}

Question

{5,x=1}
{x^2,x>1}
Given the piecewise functions shown below, select all of the statements that are true.

A.f(5)=1
B.f(2)=4
C.f(-2)=4
D.f(1)=5

Answer 1

GRAPH IT !!!!!

when x = 5 , f(5) = 25
when x = 2 , f(2) = 4 check
when x = -2 , f(-2) = -4
when x = 1 , f(1) = 5 check

Answer 2

f(1)=5

Answer 3

F(1)=5 and f(2)=4
