for f(x) = 0.01(2)x the x is an exponent

is it A

OpenStudy (welshfella):

plug in x = 17 then x = 10 to find the values of the function for those values of x then find f(17) - f(10) and divide by (17-10)

OpenStudy (welshfella):

its not A

OpenStudy (anonymous):

1.7

OpenStudy (anonymous):

i got 1.7 dividing 17 by 10

OpenStudy (welshfella):

its 0.01* 2^17 - 0.01*2^10

OpenStudy (anonymous):

sorry i messed up

OpenStudy (welshfella):

= 1310.72 - 10.24

OpenStudy (anonymous):

option 3 seems to be the best choice

OpenStudy (welshfella):

well divide the result of the subtraction by 7

OpenStudy (anonymous):

ohhhh so its B lol

OpenStudy (welshfella):

the formula fo the average is f(17) - f(10) ---------- 17 - 10

OpenStudy (welshfella):

B

OpenStudy (anonymous):

ok thank you i understand that now
