Which of the following choices describes the function f(x)=(x^2-5)? A. parabola opens upward; vertex (0, 0); line of symmetry is x=0
B. parabola opens upward; vertex (1, 5); line of symmetry is x=1
C. parabola opens upward; vertex (0, -5); line of symmetry is x=-5
D. None of these choices are correct.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
