1. 9.1: GRAPHING QUADRATICS ALGEBRA 1

2. OBJECTIVES I will be able to graph quadratics: Given in Standard Form Given in Vertex Form Given in Intercept Form What does the graph of a quadratic look like? https://www.desmos.com/calculator

3. WHAT CAN I FIND FROM MY GRAPH?

5. Y-Intercept: The point where the parabola crosses the ‘y’ axis. This can be found by substituting a 0 in for ‘x’. Minimum: If lead coefficient is + (Parabola Opens Upward) then vertex is at BOTTOM. This is a minimum! Maximum: If lead coefficient is - (Parabola Opens Downward) then vertex is at TOP. This is a maximum! Domain: All ‘x’ Values Range: All ‘y’ Values Number of Solutions: This is based on # of time the Parabola CROSSES the ‘x’ axis
