Question

WILL SOMEONE PLEASE HELP? Please show all work:: Perform the indicated operations:: Let f(x) = x2 - 7x - 9. Find f(a + h) - f(a) and simplify.

Answer 1

f(a)=a^2-7a-9
f(a+h)=a^2+2ah+h^2-7a-7h-9
(a+h)^2=a^2+2ah+h^2 just so you know
2ah+h^2-7h=f(a+h)-f(a)

Answer 2

so the final answer is 2ah+g^2-7h=f(a+h)-f(a) ?....

Answer 3

h^2 not g^2 but yea.

Answer 4

oops, typo- thank you!

Answer 5

but if you simplify its h(2a+h-7)

Answer 6

ok, great- thanks!
