Question

f(x) = ((x/2)+3) and g(x) = (((3/4)-x)-2)

Then find 5f(-2)-7g(-4)

Answer 1

\[f(x)=\frac{x}{2}+3\]\[g(x)=\frac{3}{4}x-2\]So my first question to you is:
\[f(-2)=?\]

Answer 2

psyduck!

Answer 3

Sciduck.

Answer 4

i don't know how to do is

Answer 5

f(-2) means take f(x), and replace x with -2.

Answer 6

So if I were to calculate f(5), I would get
\[f(5)=\frac{\textbf{5}}{2}+3\]

Answer 7

oh thanks soo much...
