Question

f(g(-2))
f(x)=-x^3
g(x)= 1/2x^2
can anyone give me the answer and help me..

Answer 1

g(x).=1/2x^2
by putting the value of 'x' in function
g(-2)=1/2(-2)^2=?

Answer 2

\[\large\begin{array}{cl}
&f(g(2)\\
=&f\left[\frac12(2^2)\right]\\
=&f(2)\\
=&-2^3\\
=&-8
\end{array}\]

Answer 3

P.S. \(g(2)=\frac122^2=2\)

Answer 4

thank youso much :) could you help me with..
f(x) + g(x)
f(x)=3x+4
g(x)=7x-9

Answer 5

Just freaking add them together :)

Answer 6

hahah oh my gosh,, im dumb..
