.Studying for College Algebra Final. This is a practice problem. Please help and explain. Thank you.

In the function y + a [x], how would the graph look when a = 6 compared to when a = 1. Circle your answer.

a. The function will shift to the right when a = 6 from its location when a = 1

b. The function will shift upwards when a = 6 from its location when a = 1

c. The function will be considerably wider when a = 6 than when a = 1

d. The function will be considerably narrower when a = 6 than when a = 1

e. The function will open in the opposite direction when a = 6 from when a = 1
