Which of the following shows the table represents of the exponential function f(x)=5*2^x?

A) x | y B) x | y C) x | y D) x | y
0 | 5 0 | 1 0 | 10 0 | 5
1 | 7 1 | 10 1 | 20 1 | 10
2 | 9 2 | 100 2 | 40 2 | 20
3 | 11 3 | 1000 3 | 60 3 | 40

Respuesta :

The correct answer is D
When x = 0, f(0) = 5 × 1= 5

When x = 1, f(1) = 5 × 2 = 10

When x = 2, f(2) = 5 × 4 = 20

When x = 3, f(3) = 5 × 8 = 40
