Question

Which is an equation of the exponential function that goes through the points (1, 10) and (3, 2.5)? A. y = 20(0.5) x B. y = 20(2) x C. y = 5(0.5) x D. y = 5(2) x

Answer 1

Answer:

C

Step-by-step explanation:

Becuase i checked it

Answer 2

Answer:

A

Step-by-step explanation:

y = 20(0.5^x)

x = 1, y = 20(0.5) = 10

x = 3, y = 20(0.5³) = 2.5
