Question

Explain how graphing f(x) = 2x+ 4 = 6 can give you the value of x and then what is x?

Answer 1

the value of x is;

`x=5`

Step-by-step explanation:

Given the function;

`f(x)=2\sqrt[]{x+4}=6`

To solve for x by graphing, we will graph the function;

`\begin{gathered} f\mleft(x\mright)=2\sqrt[]{x+4} \\ f\mleft(x\mright)=6 \end{gathered}`

Graphing the function;

The x-coordinate of the point at which the function intercept is the value of x;

`(x,y)=(5,6)`

Therefore, the value of x is;

`x=5`
