Use the graph to answer the question below. Which function best represents the graph?
Of(x) = 32
Of(x)31
O f() = 31 - 1
Of(x) = 3 + 1

1/4 because there is 4 grades.

ratio is 2 : 9

the answer is three

13.5 : 3

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
