Question: 1- If f ( x ) =5 x 2 x +4, find the following f ( a + 1) = 2 f ( a )

1- Iff(x) =5x2x+4, find the following

f(a+ 1) =

2f(a) =

[f(a)]2=

f(a+h) =

2- Evaluatef(7), f(0), andf(6) for the piecewise defined function.

f(x) =x+4ifx< 03xifx0

f(7)=f(0)=f(6)=

3- Iff(x) =x+6andh(x) =8x4, find a functiongsuch thatgf=h.

g(x) =

4- Find the domain of the function. (Enter your answer using interval notation.)

f(x) =

1

x1
