what is the parent function for all quadratic functions? (1 point)\n○ f(x) = x³\n○ f(x) = x²\n○ f(x) = x\n○…

Brief Explanations:

A quadratic function is of the form $f(x)=ax^{2}+bx + c$ ($a\neq0$). The simplest form, or the parent function, has $a = 1$, $b=0$, and $c = 0$, which is $f(x)=x^{2}$.

Answer:

$f(x)=x^{2}$ (corresponding to the option where $f(x)=x^{2}$ among the given choices, although the formatting of the options in the image is not clear - assuming the second option was meant to be $f(x)=x^{2}$)
