Y-interceptY intercerpts are when the line of the parabola touches the y axis. To solve for the y intercept, you will substitute the ‘x=0’ in the equation.
Minimum/Maximumminimum value= lowest point (found on vertex) of the parabolamaximum value=highest point(found on vertex) of the parabola

QuadraticThe quadratic formula is y=ax2+bx+c where a b and c cannot equal to 0 5x^2-4x+2 is a quadratic equation 5x^3-4x+2is not a quadratic equation since the exponent of the a value is 3 and not 2
standard form: ax2+bx+c=0 is another form of quadratic equation, where "a" is the coefficient -a positive value means the prabola is going upwards-a negative value means the parabola is going downwards-the standard form demonstatres width/narrowness, the direction in which it opens and the graphs vertexFactored form: when a number is broken down into its factors, it's called factored form. -the x-intercept or zeros of the function can be identified using factored form-every quadratic can technically be factored
Some things to know about...
to find the qudratic equation from a graph, there are two simple methods that can be used: using 2 p. using this formula, all we need to do -is subsitude in the vertex along with the other point-solve for a -then rewrite our final equation
And lastly you would need to know how to determine the equation of a quartic function from a graph
OMG THANK YOU MATH GOD JUST BECAUSE OF YOU I KNOW IM GOING TO DO GOOD TOMORROW
Well they do call me the math god for a reason. Good luck on your test tomorrow kid you're gonna do amazing!
