Question

Find the average rate of change for the function over the given interval.
y=4x^2 between x=0 and x = 7/4

Answer 1

if f(x) = 4x^2, then average rate of change is given by:

[ f(7/4) - f(0) ]/ (7/4 - 0)

Answer 2

how do you do it with fractions im so lost

Answer 3

f(7/4) = 4*(7/4)^2
= 4 * (7/4) * (7/4)
= 49/4

can you give me f(0) = ?

Answer 4

wait you dont multiply 4 times 4? u only square the numerator?

Answer 5

that exponent is only for the 7/4...
