The parabola passes through coordinates left parenthesis negative 6 comma negative 1 right parenthesis, left parenthesis negative 5 comma negative 6 right parenthesis, left parenthesis negative 3 comma negative 10 right parenthesis, left parenthesis negative 1 comma negative 6 right parenthesis, and left parenthesis 0 comma negative 1 right parenthesis.

Which of the following is true based on the graph of the quadratic?

(1 point)

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

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

The a-value is negative.

The vertex is located at (3,−10)

Answer 1

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

Reason: c is the y-intercept (value at x=0), and the graph includes (0, −1) so c = −1. The vertex is at (−3, −10) (not (3, −10)), so the −10 option and the given vertex choice are wrong, and the parabola opens upward (vertex is a minimum) so a > 0 (not negative).
