5 units left

The transformation f(x)f(x)7f(x) \longmapsto f(x) - 7 translates the graph in which direction?

7 units down

The transformation f(x)f(x)f(x) \longmapsto f(-x) reflects the graph in which axis?

yy-axis

The transformation f(x)4f(x)f(x) \longmapsto 4f(x) stretches the graph by what scale factor?

SF 4 parallel to yy-axis

The transformation f(x)f(5x)f(x) \longmapsto f(5x) stretches by what scale factor?

SF 15\frac{1}{5} parallel to xx-axis

Translating y=x2y = x^2 by (0,3)(0, 3) gives which equation?

y=x2+3y = x^2 + 3

Reflecting y=x3y = x^3 in the xx-axis gives which equation?

y=x3y = -x^3

For f(x)2f(x)+5f(x) \longmapsto 2f(x) + 5, does the order of transformations matter?

Yes, both affect yy
