Answer

Option D

Step-by-step explanation:

Given the first table

x 0 1 2 3

y 0 7 14 21

The standard form ofa linear function is given as

y = mx + b

Firstly, find the slope

Slope = rise / run

Rise = y2 - y1

run = x2 - x1

Slope = y2 - y1/x2 - x1

let x1 = 0, x2= 1, y1 = 0 and y2 = 7

Slope = 7 - 0 / 1- 0

Slope = 7/1

Slope = 7

(y - y1) = m(x - x1)

y1 = 0 and x1 = 0

y - 0 = 7(x - 0)

y - 0 = 7x - 0

y = 7x

For the second table

x 0 1 2 3

y 1 2 4 8

Step 1: Find the common ratio

Common ratio = y2/y1

2/1 = 2

4/2 = 2

8/ 4 = 2

Therefore, the common ratio is 2

The standard form of an exponential function is given as

y = a(b)^x

b = 2, a = 1

y = 1 * (2)^x

y = 2^x

For linear function

y = 7x

Exponential function

y = 2^x

Find the greatest value when x = 10

y = 7(10)

y = 70

y = 2^10

y = 1,024

Therefore, the function that has the greater value when x = 10 is the exponential function
