The 'template' for a quadratic function is:

, where <em>a</em> is the vertical stretch/compression factor.
If the <em>a</em> in f(x) is 2/5, then vertically stretching the function is done by multiplying the function by 2, making:
Answer:
5/4 8.10.............0.0 5=7=9
Answer:
38°
General Formulas and Concepts:
<u>Geometry</u>
- Vertical Angles Theorem - vertical angles are congruent
Step-by-step explanation:
From the graph given, we see that angle x° and angle 38° are vertical.
Therefore, using the Vertical Angles Theorem, we can say that they are congruent and x = 38°.
Answer : Last option
Tanx =48/80
Tan(angle) = opposite/adjacent
Tanx = 48/80
