Answer: f(3.5) = 58.20

Step-by-step explanation:

Wow...what degree of exponent are we to assume?

I'll go with 2 as we are only given two exemplars.

f(x) = x² + Ax + B

f(- 2.5) = 9 = (-2.5)² + (-2.5)A + B

f(2.5) = 45 = (2.5)² + (2.5)A + B

we can subtract the first equation from the second

45 - 9 = 2.5² - (-2.5)² + 2.5A - (-2.5A) + B - B

36 = 5A

A = 7.2

45 = (2.5)² + (2.5)7.2 + B

B = 20.75

F(3.5) = 3.5² + 7.2(3.5) + 20.75 = 58.2

What is the equation of the line that passes through the points (0, 3) and
madreJ [45]
First you must find the slope, by using the equation y2-y1/x2-x1
then you plug the slope and one of the given points into the equation
y-y1=m(x-x1)
so the answer is
y-3=-4/5(x-0)
