Question

Please I really need help on these two

Answer 1

1) 5

2) (3 , 24)

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
