Question

I need help with my math

Answer 1

To solve for the value of x from the graph:

`\text{when f(x) = 3}`

From the desmos graph,

y = 2x - 1

Now let's set y = 3:

`\begin{gathered} y=2x-1 \\ 3=2x-1 \\ 3+1=2x \\ 4=2x \\ x=(4)/(2) \\ x=2 \end{gathered}`

Therefore when f(x) =3 the value of x is 2
