Quadratic formula calculator to find x intercepts. In general you can skip the multiplication sign so 5x is equivalent to 5 x. Sketch the graph of the quadratic function color blue f x x 2 2x 3 solution. In general you can skip parentheses but be very careful. Shows you the step by step solutions using the quadratic formula.
About graphing quadratic functions. Quadratic function has the form f x ax 2 bx c where a b and c are numbers. You can sketch quadratic function in 4 steps. The calculator will find the x and y intercepts of the given function expression or equation.
I will explain these steps in following examples. E 3x is e 3x and e 3x is e 3x. Write down the new equation ax squared bx c 0 and the quadratic formula that gives the solution as x b plus or minus the square root of b squared 4ac all divided by 2a. To find the x intercepts the calculator solves the quadratic equation ax 2 bx c 0 using the quadratic formulas.
This calculator will solve your problems. The y intercept if given by f 0 c. X1 b δ 2 a x2 b δ 2 a where δ b 2 4 a c is the discriminant. To find the x intercepts of a quadratic equation let y 0.
