Question

The functions , F , G and H are defined as follows.
f(x)=-5+√(x-2) g(x)=-6+2x^2/x^2
h(x)=2|-9+x|

Find F(4) ,G(-2) , and H(4) .

Simplify your answers as much as possible.

Answer 1

\[h(-4)=2|-9-4|=2|-13|=2\times 13=26\]

Answer 2

as for g, does it really say
\[g(x)=6+\frac{2x^2}{x^2}\]?

Answer 3

g(x) (-6+2x^2)/x^2

Answer 4

The first one you did is :h(4)=2|-9+4|

Answer 5

then i made a mistake.

Answer 6

answer should be 10 in that case

Answer 7

Thank you, how do I solve this problem....if you don't mind ?
