Answer:

See below

Explanation:

It seems to be a typo.


f(x)=2x-31+2


f(x)=2x-29

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


0=2x-29


x=(29)/(2)

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


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