Front

What is g(-4)?

Back

-2

Answer explanation

From the origin, (0,0)

count left to negative four. Move down 2 to meet the function.

Down 2 from zero

g(-4)=-2

Front

What is g(2)?

Back

1

Answer explanation

From the origin, move right to x=2

now move up one to reach the function

y=1

g(2)=1

Answer explanation

h(0) means x=0

each equation has an inequality

substitute x in the inequality and look for the true statement

since 0<5 then we use the top equation
