Question

find the slope at 9-x^2 at x=2

Answer 1

do you know how to find the derivative?

Answer 2

no but i should use the f(a+h)-f(a)/h

Answer 3

formula

Answer 4

can u just give the function i will do rest of it

Answer 5

well, f(x) = 9-x^2

does that help?

Answer 6

nope

Answer 7

i know that

Answer 8

\[\lim_{h \rightarrow 0} f(a+h)-f(a)/h\]

f(a+h)=9-(a+h)^2
f(a)=9-a^2

does that help?

Answer 9

i figured it out myself thx for ur support
