Web16 aug. 2024 · 6 Answers Sorted by: 0 If the graph of function $f$ is a parabola then its universal form is:$$f (x)=ax^2+bx+c$$ where $a,b,c$ denote constants and $a\neq 0$. If it is known that it has zeros $x_1$ and $x_2$ exist then we can write this also as:$$f (x)=a (x-x_1) (x-x_2)$$where $a,x_1,x_2$ are constants and $a\neq 0$. WebIf you want to find out the zeros, then you substitute 0 for y and solve for x by converting it into factored form. You have to convert the function into either standard, vertex, or …
