Based on the model you chose, select the response that best tells how long it will take a delta plane once in the air flying at full speed to travel 1 mile.

hint: the model includes both flying time and time on the ground.

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
