Studdy Solution
STEP 1
Assumptions1. The graph of is a parabola opening upwards with vertex at the origin.
. The graph of is a curve starting from the origin and increasing as x increases.
3. Shifting a graph left or right involves changing the x-coordinate of each point.
4. Shifting a graph up or down involves changing the y-coordinate of each point.
5. Stretching a graph involves increasing the distance of each point from the origin.
6. Shrinking a graph involves decreasing the distance of each point from the origin.
STEP 2
For (a), the graph of can be obtained from shifting the graph of .
The change is in the x-coordinate, so the shift is horizontal. The sign of the number inside the parentheses is positive, so the shift is to the left.
STEP 3
For (b), the graph of can be obtained from shifting the graph of .
The change is in the y-coordinate, so the shift is vertical. The number added to the function is positive, so the shift is upward.
STEP 4
For (c), the graph of can be obtained from the graph of .
The change is a multiplication factor on the y-coordinate, so the change is vertical. The factor is greater than1, so the change is a stretching.
STEP 5
For (d), the graph of can be obtained from the graph of .
The change is inside the square root, affecting the x-coordinate, so the change is horizontal. The factor inside the square root is greater than1, so the change is a shrinking.
STEP 6
So, the answers are(a) left(b) upward(c) stretching(d) shrinking
