Please write x^2, not x2.
If you stretch the graph of y=x^2 vertically by a factor of 4, the resulting graph represents the quadratic function y = 4x^2. It's still a parabola, but appears to be thinner.
This particular question is about horizontal stretching, however. Stretching the graph horizontally by a factor of 4 results in the new function g(x) = (x/4)^2. Try graphing x^2 and also (x/4)^2 on the same set of axes to observe this phenomenon.
Answer:
640pi
Step-by-step explanation:
440pi + 200pi= 640pi
I can’t tell what those options are.
The domain is the input values of a function, therefore the x values.
In this case the interval for the domain is
-4< x <= 4
Answer:
18√(2y)
Step-by-step explanation:
The common factor √(2y) can be factored out, and its coefficients combined.
<h3>Simplification</h3>
The root itself cannot be simplified in this case.
Answer:
There are 20 ways but I will give you 4 :)
1. Multiply the numerator and the denominator by 2:
5/7 x 2/2 = 10/14
2. Multiply the numerator and the denominator by 3:
5/7 x 3/3 = 15/21
3. Multiply the numerator and the denominator by 4:
5/7 x 4/4 = 20/28
4. Multiply the numerator and the denominator by 5:
5/7 x 5/5 = 25/35
Step-by-step explanation:
There you go!
