Question

find the slope of the line tangent to the graph of the function g(x)=9-x^2 at the point (4,-7)

Answer 1

slope = g'(x = 4)

find g'(x), first

Answer 2

the derivative of 4 is 0 @RadEn

Answer 3

g(x) = 9 - x^2
g'(x) = -2x

then slope = g'(x=4) = -2(4) = -8

Answer 4

thank you!

Answer 5

welcome

Answer 6

ok @RadEn the next question is find the slope of the line tangent to the graph of the function f(x)=3-7x at the point (-1,10). would it be -7?

Answer 7

you are right :)

Answer 8

thanks!

Answer 9

you're welcome
