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
