This graph represents a quadratic function. The value of a, in this function’s equation, will be -1. Option D is correct.
What is a function?
A connection between independent variables and the dependent variable is defined by the function. Functions help to represent graphs and equations.
A quadratic function is represented by this graph. In this function's equation, the value of a will be -1.
The function is
ax²+bx+c=0
The given point for the functions are,(0,9),.(-3,0)(3,0).
Substitute the different values;
9=0+0+c
0=9a+3b+c
0=9a-3b+c
The values we obtained after solving the equations;
a=-1
b=0
c=9
This graph represents a quadratic function. The value of a, in this function’s equation, will be -1.
Hence, option D is correct.
