1 Determine if a relation is a function.
4 Evaluate a function for given value.
Created notes on 4 Function Families based on results of small investigation lesson on Thursday.
Linear Functions y = x, the x is just an x, example y = 3x – 2; the graph will be a straight line.
Quadratic Functions y =- x^2, the x is squared, example y = 3x^2 +4; the graph will be a parabola or u-shaped graph.
Exponential Functions y = a^x, the x is the exponent or power, example y = 3.1^x; the graph will look like a “slide” or “ramp”.
Absolute Value Functions y = |x|, the x is inside the absolute value, example y = |x+2|; the graph will have a “v-shape”
Whole Class Assessment
Individual Student Assessment at the board – matching equation & graph to function family.
