Question

Prompt

The relationship between the variables

x

and

y

is defined by an exponential equation. When

x = 0

the value of

y

70

, and for every increase in the value of

x

1

, the corresponding value of

y

increases by

50%

of its previous value. Which equation represents this relationship?

y = 70 (1.50)^{x}

y = 70 (1.05)^{x}

y = 50 (1.70)^{x}

y = 50 (1.07)^{x}
