Answer:
1) 5
2) (3 , 24)
Step-by-step explanation:
Question 1
f(x) x= 1 2 * 5¹ = 10
f(x) x= 2 2 * 5² = 50
f(x) x= 3 2 * 5³ = 250
multiplicative rate of change = 50/10 = 5
check: 250/50 = 5
Question 2
f(x) = 2 * 4ˣ
(3 , 24) f(3) = 2 * 4³ = 2 * 64 = 128 ≠ 24
Answer:
perform cross multiplication:
Answer:
2.7g-1
Step-by-step explanation:
You have to searh the x values that make f(x) = 0
Factoring this equation is very difficult.
You can divide by x+3 and you will find that the equation can be factored as
(x+3)(x-4)^2
That means that x = -3 and x = 4 make f(x) = 0
Then the points are (-3,0) and (4,0).
