Identify a, b, and c in the given quadratic function. What does the value of a tell you about the function?
Minimum Value: - 23.5
Domain: {all real numbers}
Range: {f(x)|f(x)≥ - 23.5}
Let's begin by rewriting our function in the general expression of a quadratic function, f(x)=ax^2+bx+c. f(x) = 2/3x^2+6x-10⇔ f(x) = 2/3x^2 +6x +(- 10) We can see that a = 23, b = 6, and c = - 10.
In the given function, we have a=23, which is greater than 0. Thus, the parabola will have a minimum value.
x= - 9/2

Unless there is a specific restriction given in the context of the problem, the domain of a quadratic function is all real numbers. In this case, there is no restriction on the value of x. Since the minimum value of the function is - 23.5, the range is all real numbers greater than or equal to - 23.5. Domain:& {all real numbers} Range:& {f(x)|f(x)≥ - 23.5}
