Standardized Test Practice

Exercise 1 Page 222

When a graph is translated down, the y-coordinate of the points change by the same amount.

G

Practice makes perfect

When the graph of y=g(x) is translated down by 5 units, we get the graph of y=g(x)-5.

h(x)=g(x)-5

g(x)= 2/5x^2-4x+2

h(x)= 2/5x^2-4x+2-5

Subtract terms

h(x)=2/5x^2-4x-3

When the graph of g(x)= 25x^2-4x+2 is translated down by 5 units, we get the graph of h(x)= 25x^2-4x-3. The correct answer is G.
