CR3. An object is launched at 19.6 meters per second (m/s) from a platform. The equation for the object's height s at time t seconds after launch is s(t) = -4.9t? + 19.6t + 58.8, where s is in meters. Answer the following questions based on this information. a. How high is the object after 1 second? b. How tall is the platform? c. When does the object hit the ground? d. What is the maximum height of the object? e. When does it reach its maximum height?

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.
