Without graphing, predict whether the function, y = 3(0.2)x, shows exponential growth or decay. justify your predictions.

a. decay; because 0.2 < 1
b. growth; because 0.2 < 1
c. decay; because 0.2 > 1
d. growth; because 0.2 > 1

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
