Not my work but found answer key to answer u need.
Answer:
875
Step-by-step explanation:
lets assume the original amount X
the new amount = X - ( X × 40% )
525 = (60 × X) ÷ 100
X = ( 525 × 100 ) ÷ 60
<u>X = 875</u>
Do I have to do all of them?
The greatest outputs will be by function h.
Hope this helps.
Vertex = 2, -9
Intercept = 0, -5
You can find this by distributing the parenthesis and then finding the vertex using -b/2a.
