Question

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

Answer 1

Answer:

the value of x is;

$x=5$

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;

$x=5$
