Given the function f(x) = 4x^2 - 10x + 9, What is the average rate of change for f ove rthe interval 2.6 le x le 5.2?

(le means less than or equal too btw :))

Thank you so, so much if you can take any time to help me, if not that's ok too though

The average rate of change of f over the interval 2.6 ≤ x ≤ 5.2 is the slope of the blue dotted line on the above graph.

The blue dotted line passes through the purple point, (2.6, f(2.6)) , and the green point, (5.2, f(5.2))

Do you know how to find the slope of the blue dotted line? (Remember "rise over run" )

Uhhh I think I did something wrong :PP I got (15-5)\(3-2) = 10 as the slope but I don't think that's right.. :((
