QUESTION:

if f(x) = 3x^2(squared) then find f(4) and f(3b)

ANSWER:

if f(x) = 3x^2(squared) then find f(4) and f(3b)

f(x) = 3 ( x )^2

To find f(4), replace x by 4 in the given equation as follows.

==> f(4) = 3 ( 4 )^2

==> = 3 * 16

==> = 48

To find f(3b), replace x by 3b in the given equation as follows.

f(3b) = 3 ( 3b )^2

= 3 * 9 b^2

= 27 b^2

If the second question is f(3),

f(3) = 3 ( 3 )^2

= 3 * 9

= 27

Hope you understood.
