Question

Sammy is going to graph y = ex + 3. Before he graphs, he writes down what he thinks will happen to the parent graph. Which statement is correct?
A)The graph is translated up 3 units.
B)The graph is translated down 3 units.
C)The graph is translated to the left 3 units.
D)The graph is translated to the right 3 units.
E)The graph is translated down 3 units and right 1 unit.

Answer 1

think about how that would effect the x and y coordinates...

y=e^x has a certain domain and range

if you add 3 , y = e^x +3

the x values are unchanged, every y value is changed by that +3

Answer 2

y direction shift...

(x , f(x)) -----> (x , f(x) + b)
