Answer:

A

Step-by-step explanation:

A.y=x/2 - 5  => y = (1/2)x - 5.  Here x is to the first power.  This is a linear function.

B.y=2^x - 1  Thanks to the 2^x term, this is an exponential function.

C.y=x^2+7   Thanks to the x^2 term, this is a quadratic function.

D.y=2/x+3  Non-linear,  Similar to y = 2x^(-1) + 3
