A parent function is a basic function that serves as a foundation for a family of functions. The quadratic function, represented by ( f(x) = x^2 ), is indeed a parent function that produces a parabola when graphed. However, there are other parent functions as well, such as linear functions and cubic functions, which produce different shapes. Therefore, while the parabola is one type of parent function, it is not the only one.
The quadratic parent function, represented by ( f(x) = x^2 ), produces a parabolic graph that opens upward, while the square root function, represented by ( g(x) = \sqrt{x} ), results in a graph that starts at the origin and increases gradually. Both functions are defined for non-negative values of ( x ), but they exhibit different characteristics: the quadratic function is symmetric and continuous, whereas the square root function has a domain of ( x \geq 0 ) and increases at a decreasing rate. Overall, they are distinct types of functions with different shapes and behaviors.
In algebra, several parent functions pass through the origin, including the linear function ( f(x) = x ), the quadratic function ( f(x) = x^2 ), and the cubic function ( f(x) = x^3 ). Additionally, the absolute value function ( f(x) = |x| ) and the identity function also intersect at the origin. These functions exhibit key characteristics that define their respective families.
When a function is nested inside another function, the outer one is the parent, the inner is the child.
parent
The minimum is the vertex which in this case is 0,0 or the origin. There isn't a maximum.....
x2
A parent function refers to the simplest function as regards sets of quadratic functions
y = x2 is the parent function, but it can be in the form y = ax2 + bx + c
vertex
Parabal
The global minimum value is always negative infinity.
The domain is all real numbers, and the range is nonnegative real numbers (y ≥ 0).

g(x)=x^-2 thanks go like my youtube MATH VIDEOS TO GET HELP
The parent function of the exponential function is ax
Reciprocal parent function
