It depends on the equation.
You need more than one tangent to find the equation of a parabola.
Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.
To find the x-intercept you need to set y=0 in your equation. To find the y-intercept you need to set x=0 in your equation.
Your equation must be in y=ax^2+bx+c form Then the equation is x= -b/2a That is how you find the axis of symmetry
