Question

What is the average rate of change of y with respect to x over the interval [1, 5] for the function y = 4x + 2?

Answer 1

know the formula for rate of change?

Answer 2

\(\Large \dfrac{f(b)-f(a)}{b-a}\)

Answer 3

a,b = 1,5
f(x) =4x+2

Answer 4

Average change=[f(5)-f(1)] /(5-1)

Answer 5

oh ok yeah I didnt knw the formula thanks! I got 1/4

Answer 6

1/4 or 4?

Answer 7

1/4

Answer 8

then show your steps?

Answer 9

f(5) = 4*5+2 = 22
f(1) = 4*1 +2 = 6

numerator = 22-6 =16

denominator = 5-1 =4

Answer 10

Thank you! so it's 4

Answer 11

yes, welcome ^_^
