To vertically stretch the parent function \( f(x) = x^2 \) by a factor of 3, we can express this as follows:
\[ y = kf(x) = 3x^2 \]
Now, we can complete the table for \( y = 3f(x) \):
Table for \( y = 3x^2 \)
| x | y = 3f(x) = 3x^2 | |-----|----------------------| | 0 | 3(0^2) = 0 | | 1 | 3(1^2) = 3 | | 2 | 3(2^2) = 12 |
Now, we move onto the next part of your request, which involves vertically compressing the parent function \( f(x) = x^2 \) when \( k = \frac{1}{2} \):
\[ y = kf(x) = \frac{1}{2}x^2 \]
Now, we can complete the table for \( y = \frac{1}{2}x^2 \):
Table for \( y = \frac{1}{2}x^2 \)
| x | y = \frac{1}{2}f(x) = \frac{1}{2}x^2 | |-----|------------------------------------------| | 0 | \(\frac{1}{2}(0^2) = 0\) | | 1 | \(\frac{1}{2}(1^2) = \frac{1}{2} = 0.5\) | | 2 | \(\frac{1}{2}(2^2) = \frac{1}{2}(4) = 2\) |
Summary of Both Tables
-
Vertical Stretch by 3:
- When \( y = 3x^2 \):
- \( x = 0 \), \( y = 0 \)
- \( x = 1 \), \( y = 3 \)
- \( x = 2 \), \( y = 12 \)
- When \( y = 3x^2 \):
-
Vertical Compression by \( \frac{1}{2} \):
- When \( y = \frac{1}{2}x^2 \):
- \( x = 0 \), \( y = 0 \)
- \( x = 1 \), \( y = 0.5 \)
- \( x = 2 \), \( y = 2 \)
- When \( y = \frac{1}{2}x^2 \):
