The height of a projectile fired vertically into the air neglecting air resistance at an initial velocity of 64 feet per second is a function of the time (t) and is given by the equation h(t)=64t16t2 Compute h(1), h(2), h(3) and h(4).

Graph the function f(x)=5(0.5)x and its reflectionacross the y-axis on the same axes, and give they-intercept.

The graph of f(x)=10x is reflected about the x-axisand shifted upward 7 units. What is the equation ofthe new function, g(x) ? State its y-intercept, domain,and range.

Graph: f(x)=x2+1.

During a nine-hour snowstorm, it snows at a rate of 1 inch per hour for the first 2 hours, at a rate of 2 inches per hour for the next 6 hours, and at a rate of 0.5 inch per hour for the final hour. Write and graph a piecewise-defined function that gives the depth of the snow during the snowstorm. How many inches of snow accumulated from the storm?

Use your schools library, the Internet, or some other reference source to find real-life applications of approximations of functions.
