Question

f(t)=3t^2-2 find f(k-2)

Answer 1

replace \(t\) by \(k-2\) be sure to use parentheses

Answer 2

so if \(f(t)=3t^2-2\) then \(f(k-2)=3(k-2)^2-2\)
you can clean that up with some algebra if you like

Answer 3

ok so then it would be 3k^2+12-2

Answer 4

no, you have to square first, multiply second, then combine like terms

Answer 5

no

Answer 6

\[f(k-2)=3(k-2)^2-2=3(k-2)(k-2)-2\] etc
there is algebra to do

Answer 7

3(k−2)^2−2 would be 3(k-2)(k-2) -2

Answer 8

yes

Answer 9

yes exactly

Answer 10

3(k^2-2k-2k+4)-2

=3k^2-12k+10

Answer 11

You got it :D

Answer 12

are u kidding me, i got a warning for my steps?? this is rediculous
