The formula d=t^2+3t expresses a car's distance (in feet) from a stop sign, d, in terms of the number of seconds t since it started moving. Determine the car's average speed over each of the following intervals of time. From t=3 to t=6 seconds... feet per second 2. From t=6 to t=6.5 seconds... feet per second 3. From t=6.5 to t=7 seconds... feet per second

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
