What is the equation in standard form of a parabola that models the values in the table y=-4x^2+3x+5 y=-4x^2-3x+5 y=3x^2-4x+5 y=4x^2-3x+5

Y=4x^2-3x+5

Step-by-step explanation:

For the standard form equation to model the values in the table, each value of x in the table should give the matching the y value when substituted into the equation. We will test each equation:

for (-1,12)

This does not give 12 as the answer and is not a solution.

for (-1,12)

This does not give 12 as the answer and is not a solution.

for (-1,12)

This does give 12 as the answer and is a possible solution.

We now try (2,15).

This does not give 15 as the answer and is not a possible solution.

for (-1,12)

This does not give 12 as the answer and is not a solution.

We now try (2,15).

This does give 15 as the answer and is a solution.

This is the standard form of the equation.

c is the answer

step-by-step explanation:

the answer is 31.27mph
