Answer:
a) 2 b) 1 c) 7/6
Function a(x) = 2x + 3 has the greatest rate of change
Step-by-step explanation:
a(x) = 2x + 3
2(-1) + 3 = 1 (-1,1)
2(2) + 3 = 7 (2,7)
= 6/3
=2
b(x) = x^2 - 1
(-1)^2 - 1 = 0 (-1, 0)
(2)^2 - 1 = 3 (2,3)
= 3/3
=1
c(x) = 2^x + 1
2^(-1) + 1 = 1.5 (-1, 1.5)
2^(2) + 1 = 5 (2,5)
= 3.5/3 or 7/6
=7/6
Answer:
9
Step-by-step explanation:
Cost of tablet $315
monthly payments of $25
a. 315 - 25 = $290
b. After each payment, the amount owed decreases. Therefore, the balance decreases.
second part of this: write equation for calculating the amount owed a for any number of payments n $ $25(n-1) =a
I cant draw a graph on here for you, but as n increases, then a decreases
d. as n increases by 1, how does a change? Answer: A decreases by $25 each time n increases by one
e. He will need to make 12.6 payments
The answer is 28.27 cm because the formula for area of a circle is A=

*r^2. Hope this helped!
