F(x)= 1/2 x + 3 a linear, quadratic, exponential function or none of those

linear

The problem:

is linear, quadratic, exponential, or none of these?

Step-by-step explanation:

If the function is then f is linear.

It is linear because it is a polynomial with first degree.

It is linear because you can compare it to the slope-intercept form of a linear equation which is y=mx+b.  We see thatm=1/2 and b=3.

Example of  quadratics:

All the functions a through d are quadratics because they are polynomials with degree 2.

Also each one of them are comparable to the quadratic expression:

.

Examples of exponential:

Notice all of these have a variable exponent on a constant base.
