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

y = -3.5x² + 2.7x -8.2

Step-by-step explanation:

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

Step-by-step explanation:

Quadratic functions are always formatted in the form .

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 .

B is 2.7, so the second term is

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

So we have
