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

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

The vertex is located at (3,−10)

The vertex is located at left parenthesis 3 comma negative 10 right parenthesis

The a-value is negative.

Answer 1

The c-value is −1.

Reason: In standard form y = ax^2 + bx + c, c is the y-intercept (the value at x = 0). The graph crosses the y-axis at (0, −1), so c = −1.
