A. In the following function defined by an equation in the form y = ax^2+bx+c, identify the values of a, b, and c.
y = 5x^2 + 2x - 1
a = -1, b = 2,c = 5
b. a = -2,b = 5.c - 1
c. a = 1, b = 5,c = 2
d. a =5, b = 2, c = -1

d

Step-by-step explanation:

by substitution what is before x² is considered as a

what is before x is b and the number alone(without x) with it's sign included is c

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8
