Answer: a = 1.25, b = 2.5, c = 1.25

Step-by-step explanation:

Use vertex form and substitute a point into it (1, 5)

5 = a(1 + 1)^2 + 0

5 = a(2)^2 + 0

5 = 4a

a = 5/4

y = 5/4 (x + 1)^2

y = 5/4 (x^2 + 2x + 1)

1.25 x^2 + 2.5x + 5/4

Is there a "c" value otherwise it's not possible

What is the value of this expression when n approaches infinity?
topjm [15]

ANSWER

C. 35

EXPLANATION

The given expression is:

15 - 35 -  \frac{85}{n}  + 55 +  \frac{75}{2n}  +  \frac{15}{2 {n}^{2} }

As

n \to \:  \infty

\frac{k}{n}  \to0

where k is a constant.

This implies that,

15 - 35 -  \frac{85}{n}  + 55 +  \frac{75}{2n}  +  \frac{15}{2 {n}^{2} }  = 15 - 35 -  0 + 55 +  0+  0 =35

The correct answer is C
