Camilla entered the following group of values into the tvm solver of her
graphing calculator. n = 24; 1% = 1.2; pv = ; pmt = -480; fv = op/y = 12; c/y
= 12; pmt: end. which of these problems could she be trying to solve?

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
