Question

For the following Function, Evaluate the function F at the values f(-1) and f(2)

Answer 1

the given expression is

`f(x)=3+\sqrt[]{x+3}`

now put x = -1 for evaluate f(-1)

`\begin{gathered} f(-1)=3+\sqrt[]{-1+3} \\ f(-1)=3+\sqrt[]{2} \end{gathered}`

for f(2) put x = 2 in the equation

`\begin{gathered} f(2)=3+\sqrt[]{2+3} \\ f(2)=3+\sqrt[]{5} \end{gathered}`

the expression is

`f(x)=3^x`

put x = -1

`f(-1)=3^(-1)=(1)/(3)`

put x = 2

`\begin{gathered} f(2)=3^2=3*3=9 \\ f(2)=9 \end{gathered}`
