Question

Evaluate ƒ(x) when x = 6.
9
37
109
6

Answer 1

It should be 6
Because as equation says we have to take 6 when x is from 6 to 9 including 6

Answer 2

f(x)=6 at x=6

Therefore, option 4 is correct.

Explanation:

We have been given a function:

`f(x)=  [tex]f(x)=\begin{cases}3x^2+1 & \text{ if } -4<x<6 \\ 6 & \text{ if } 6\leq x<9 \end{cases}`

We have to find the value of f(x) where x =6

The function is 6 at x= 6 from the definition of the function. Because equal to sign is with 6

Therefore, option 4 is correct.
