Question

5. Find the slope of the secant to the curve f(x) = 0.25(4)^x - 2 between:

i) x = 0 and x = 1
ii) x = 0 and x = 0.5
iii) x = 0 and x = 0.1
iv) x = 0 and x = 0.01

Answer 1

is it
f(x) = .25(4^x) - 2 , which is what it would be according to your typing
or , is it

f(x) = .25(4)^(x-2) , I think that is what you wanted

let me know before I work at it.

Answer 2

It's f(x) = .25(4^x) - 2
Thank you!
