f(x) = 2(5)ˣ
You can tell from the given equation that (5) is the multiplicative rate of change because 5 is the value being raised to the x-power.
Let's see if that is true:
x y
1 10 (10 x 5 = 50) so next y-value should be 50.
2 50 (50 x 5 = 250) so next y-value should be 250.
3 250
Can you calculate what the next ccordinate will be? (4, ____) (250 x 5 = 1250)
Answer: 5
