Question

IM LOST PLEASE HELP!
What are the values of a, b, and c in the function?
List them in order with commas, such as 1,-2,3.
y = -2x2 + 5x - 4

Answer 1

a , b , and c are variables that are assigned to the coefficients of the function...

y = -2x² + 5x - 4

The first coefficent...is -2...it comes before the x²

The second coefficient is 5...comes before the x

And the third coefficient is -4...the constant counts as one too yes..

so

a = -2
b = 5
and
c = -4

Answer 2

This equation is written in the form

\[y = ax^2 + bx + c\]

if that helps put a visual with the explanation at all :)

Answer 3

so all I do it put them in order right or do I figure it out first?

Answer 4

I'm not sure what you have to figure out...I thought all we needed was to find the values of a, b and c

Since your equation is

\[y = -2x^2 + 5x - 4\]

And that is in the form

\[y = ax^2 + bx + c\]

Your answers would be

a = -2
b = 5
and
c = -4

Answer 5

so it would be -4, -2, 5?

Answer 6

Oh okay I see what you're saying...

a , b , c

-2, 5, -4

These are used for the quadratic equation

Answer 7

okay thank you!
