The value of f(-3) is -9 for the quadratic function graphed.
What is a function?
It is defined as a special type of relationship and they have a predefined domain and range according to the function.
We know that if we plot a quadratic function on the coordinate plane we will get a parabola graph and the standard expression for the parabola:
[tex]\rm f(x)=ax^2+bx+c[/tex]
Where a, b, c are real numbers and a ≠ 0
The value of f(-3) means the value of y on the coordinate plane when [tex]\rm x = -3[/tex]
From the graph, we can see the value of y when x = -3
Therefore,
f(-3) = -9
Thus, the value of f(-3) is -9.
