Order the functions from narrowest graph to widest.
8. f(x) = 5x2; g(x) = 2x2
9. f(x)= {x?; g(x)= -3x?; H(x)= x2
Compare the graph of the function with the graph of f(x)=x?
10. g(x) = 2x2 + 4

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
