Question

Which quadratic function in standard form has the value a= -3.5, b=2.7, and c= -8.2?

Answer 1

`-3.5x^2 + 2.7x -8.2`

Explanation:

Quadratic functions are always formatted in the form
`ax^2+bx+c`.

So, we can use your values of a, b, and c, and plug them into the equation.

A is -3.5, so the first term becomes
`-3.5x^2`.

B is 2.7, so the second term is
`2.7x`

And -8.2 is the C, so the third term is
`-8.2`

So we have
`-3.5x^2+2.7x-8.2`

Hope this helped!

Answer 2

y = -3.5x² + 2.7x -8.2

Explanation:

the quadratic equation is set up as a² + bx + c, so just plug in the values
