Question

The graph of this function is shifted 7 units right and shifted 5 units up.

Answer 1

Graphing

The graph of this function is shifted 7 units right and shifted 5 units up.

f(x) = -2/3(x - 7)² - 5

• True
• False

Answer:

• False

Explanation:

• Why false? As I noticed, in the equation f(x) = -2/3(x - 7)² - 5, the vertex is (7, -5). The value of a, which is -2/3, is negative. So the graph opens downwards. The graph shifts 7 units to the right, which is correct, but graphing 5 units up is wrong. Why? 5 is negative, so it should be shifted 5 units down.
