Unit 1: Functions Minds On More Graphing!!! 

Graph the following functions:
Unit 1: Functions Minds On Graph the following functions: f(x) = x2 g(x) = 3f(x) h(x) = -g(x)

Lesson 7: Stretches, Compressions, and Putting it all Together
Unit 1: Functions Lesson 7: Stretches, Compressions, and Putting it all Together Learning Goals: I can vertically stretch and compress a function. I can horizontally stretch and compress a function. I can transform a function using translations, reflections, and stretches and compressions.

Lesson 7: Stretches, Compressions, and Putting it all Together
Unit 1: Functions Lesson 7: Stretches, Compressions, and Putting it all Together How does the value “a” in the function y = af(x) change the graph of f(x)? When a > 1 f(x) is stretched vertically by a factor of a When 0 < a < 1, f(x) is compressed vertically by a factor a AND When a is negative, f(x) is ALSO reflected in the x-axis.

Lesson 7: Stretches, Compressions, and Putting it all Together
Unit 1: Functions Lesson 7: Stretches, Compressions, and Putting it all Together Let’s look at y = f(kx) WARNING! This “k” is not the same as k in y = a(x-h)2 + k

Lesson 7: Stretches, Compressions, and Putting it all Together
Unit 1: Functions Lesson 7: Stretches, Compressions, and Putting it all Together f(x) = x g(x) = f(3x) h(x) = 3f(x) Are g(x) and h(x) the same?

Lesson 7: Stretches, Compressions, and Putting it all Together
Unit 1: Functions Lesson 7: Stretches, Compressions, and Putting it all Together Graph the following functions: f(x) = x2 g(x) = f(3x) h(x) = 3f(x)

Lesson 7: Stretches, Compressions, and Putting it all Together
Unit 1: Functions Lesson 7: Stretches, Compressions, and Putting it all Together How does the value “k” in the function y = f(kx) change the graph of f(x)? When k > 1 or k < -1 f(x) is compressed horizontally by a factor of 1 𝑘 When -1 < k < 1, f(x) is stretched horizontally by a factor of 1 𝑘 AND When k is negative, f(x) is ALSO reflected in the y-axis.
