Graph the function f(x)=(x+2)^2-5. Start by graphing y=x^2

A punter kicks a football. Its height in meters is given by the function, h(t) = - 4.9t ^ 2 + 18.42t + 0.8 where represents the height (meters) and represents the time, in seconds. The height of an approaching blocker's hands can be modeled by the equation, h(t) = - 2.21t + 7.45 using the same timeCan the blocker knock down the punt? If so, at what time does this happen ?

Use the zeros to graph the function y=(x+1)(x-5)(x-4)

R(x) = 7/x^2-16   Write in lowest terms, if necessary.  Locate when the graph will cross/touch the x-axis, if necessary.
