a) Solve by factoring.
Answer:
Show work in this space.
b)Solve by using the quadratic formula. >>x2 - 6x + 8 = 0,
Answer:
Show work in this space.
2) For the function y = x2 - 6x + 8, perform the following tasks:
a) Put the function in the form y = a(x - h)2 + k.
Answer:
Show work in this space.
b) What is the equation for the line of symmetry for the graph of this function?
Answer:
c) Graph the function using the equation in part a. Explain why it is not necessary to plot points to graph when using y = a (x - h) 2 + k.
Show graph here.
Explanation of graphing.
d) In your own words, describe how this graph compares to the graph of y = x2?
Answer:
3) Suppose a baseball is shot up from the ground straight up with an initial velocity of 32 feet per second. A function can be created by expressing distance above the ground, s, as a function of time, t. This function is s = -16t2 + v0t + s0
?16 represents ?g, the gravitational pull due to gravity (measured in feet per second 2).
?v0 is the initial velocity (how hard do you throw the object, measured in feet per second).
?s0 is the initial distance above ground (in feet). If you are standing on the ground, then s0 = 0.
