Solving Quadratic EquationsComponents of Quadratic Functions Medina
Graph of a Quadratic FunctionThe solution(s) or roots of quadratic equations are the x-intercepts of the quadratic function. y = -x² + 4x -3 ( 3 , 0 ) ( 1 ,0 ) x = 3 & 1
Graph of a Quadratic FunctionThe solution(s) or roots of quadratic equations are the x-intercepts of the quadratic function. y = 3x² -18x ( 0 , 0 ) ( 6 ,0 ) x = 0 & 6
Graph of a Quadratic Function*Note: If the function only has one x-intercept therefore there is only one solution. y = x²+10x+25 ( 0 , -5 ) x = -5
Graph of a Quadratic Function*Note: If the function only has one x-intercept therefore there is only one solution. y =-4x²+16x-16 ( 0 , 2) x = 2
Graph of a Quadratic Function*Note: If the function has no x-intercept(s) than there is no real solution not zero because zero means the graph crosses at zero. y = x²+6x+10 x = No Real Solution
Finding the Intercepts of a Line
Graphs of Equations Finding intercepts of a graph Graphically and Algebraically.
If b2 = a, then b is a square root of a.
Find the x-intercept To find the y-intercept, we must use 0 for x. Substitute x = 0 into 2x + 3y = 6 and solve for y: 2x + 3y = 6 2(0) + 3y = y.
Day 5 Simplify each expression: Solving Quadratic Equations I can solve quadratic equations by graphing. I can solve quadratic equations by using.
