LO-U10T2 – #2: I can graph a cosine and secant function using transformations.
a)
Write the equation in standard form
f(x) = a cos[b(x - h)] + k where b 2 0 or f(x) = a sec[b(x - h)] + k where b > 0.
b) State the base equation and transformations.
c)
Create a table of points that moves the base graph through each of its transformations. You
must have 5 points in your table.
d) Sketch the graph using the points found in c). Be sure that the scale and spacing on the axes is
appropriate. Make your graph the size of at least 4 of a page.
e)
State the period, phase shift, and amplitude.
f) State the Domain and Range.
