Question

How do I solve this and what is the answer

Answer 1

The speed of the vehicle is modeled by

`y=9x+3`

To find the initial value from the linaer function.

If x<0, then the velocity becomes negative. But velocity of a vehicle can not be negative.

Therefore x assumes greater than or equal to 0.

Putting x=0, the value of y is 3.

Therefore, the initial value is 3

Hence the correct answer is (C)
