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

For The Following Function Evaluate The Function F At The Values F1 And F2 class=

Sagot :

the given expression is

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

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

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

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

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

the expression is

[tex]f(x)=3^x[/tex]

put x = -1

[tex]f(-1)=3^{-1}=\frac{1}{3}[/tex]

put x = 2

[tex]\begin{gathered} f(2)=3^2=3\times3=9 \\ f(2)=9 \end{gathered}[/tex]
