Answer:

See below

Step-by-step explanation:

It seems to be a typo.

[tex]f(x)=2x-31+2[/tex]

[tex]f(x)=2x-29[/tex]

The x-intercept is when the function is equal to zero. Once the function is linear, there will be one x-intercept.

[tex]0=2x-29[/tex]

[tex]x=\dfrac{29}{2}[/tex]

Once there are alternatives with two values, your function  is probably a quadratic function.

[tex]f(x)=2x^2-31x+2[/tex], but the roots are not in the alternatives.
