Exercise: Sketch the graph of y=-3
+3.
a) First, express y=-3 x-
+3 in the form y = a ·f (c(x + h)) + k where f(x)
is function that you know how to graph. f(x) is called the parent function.
y=-31 ½ (x - 2) | + 3 so y.
1/(x-21 +3
b) Sketch the graph of y = f(x). Plot at least 3 interesting points (all intercepts
should be included).
y = − 3 ) ²² (-3 - 21 | +3
=-3.1+3=0
x = 0, y = -3 | - 5
= O
(0-2)| + 3 = -3+1+3
x = 2y = -31-3 (2-2)| +3 =-3.0+3 = 3
x = 7 y = -3 | 1/3 (7-2) | +3=-3+1+3
c) Sketch the graph of y = af (cx) by dividing the x-coordinates of the curve in
Step 1 by c and multiplying the y-coordinates by a.
d) Sketch the graph of y = a f (c(x + h)) + k by subtracting h from the x-
coordinates of the curve in Step 2 and adding k to the y-coordinates.
