The a-value is negative.
The a -value is negative.

The c-value of the equation in standard form is −1 .
The c -value of the equation in standard form is negative 1 .

The c-value of the equation in standard form is −10 .
The c -value of the equation in standard form is negative 10 .

The vertex is located at (3,−10)
The vertex is located at left parenthesis 3 comma negative 10 right parenthesis

Answer 1

The true statement is: "The c-value of the equation in standard form is −1."

Reason: c is the y-intercept (value at x = 0), and the point (0, −1) is given. The vertex is at (−3, −10) (so the option (3, −10) is wrong) and the parabola opens upward (a > 0), so "a-value is negative" is false.
