Question

Need help with this

Answer 1

okay so i did the problem and i ended up with \[f(3)=\frac{ 1 }{ 3 }\]

Answer 2

How do I solve the f(3) part

Answer 3

hint: x^2 - 3 = (3^2) - 3 = ?

Answer 4

oh okay its six

Answer 5

3

Answer 6

good so f(3) = 1/6 = your answer

Answer 7

i dont do anything with the f(3)?

Answer 8

no

Answer 9

"f(3)" is just notation that means "the value of f(x) at x = 3" so by evaluating the function at x = 3 you are saying what f(3) is

Answer 10

anyway, for part b, you would just replace "x" with "h" and then evaluate what f(h) equals

Answer 11

um is it 3

Answer 12

f(x) = 1/(x^2 - 3)

^ write this down

then replace "x" with "h"

then that's your answer, you don't need to do anything else

Answer 13

so

Answer 14

\[f(h)=\frac{ 1 }{ h^2-3 }\]

Answer 15

yep that's it
