Question

Please help! what is the significance of the expression ( f(1+h)-f(1) )/h in the following graph of f when h is 9/2

Answer 1

answer choices: a. length of a line segment pt
b. slope of a line through P and T
c. slope of a tangent line at P
d, slope of a line through P and R
e equation of a line through P and R
f. length of a line segment PU
g. equation of a line through P and T
h.length of a line segment PR
I. equation of a line through P and U
J. of a line through P and U

Answer 2

j. slope of a line through P and U

Answer 3

What happens when you plug in h =9/2 into the formula?

Answer 4

9/2 = 4.5
\[\frac{f(1+4.5)-f(1)}{4.5}=\frac{f(5.5)-f(1)}{4.5}=\frac{f(5.5)-f(1)}{5.5-1}\]
That last expression look familiar (I hope)

Answer 5

slope of a line U and P

Answer 6

Yes :)
