A.
h(x)=3*5ˣ; h(0)=3, h(1)=15: rate of change is (15-3)/1=12 (1st section)
h(2)=3*25=75, h(3)=3*125=375: rate of change (375-75)/1=300 (2nd section)
b.
So the second section is 300/12=25 times greater than the first section.
The function is exponential and as x gets larger the difference between consecutive values of h(x) increases dramatically so the rate of change increases.
Answer:
$2.25

Answer:
Step-by-step explanation:
1000($1500(0.40)) = $600 000
450($1500(0.25)) = $168,750
600,000 - 168,750 = $431,250
$431,250 / 550 = 784.0909090... $784.09
$1500 + $784.09 = $2,284.09
