Consider the function f(x) = x2 and the function g(x) = 3x2. How will the graph of g(x) differ from the graph of f(x)?
Select the correct answer
The graph of g(x) is the graph of f(x) shifted to the left 3 units.
The graph of g(x) is the graph of f(x) stretched vertically by a factor of 3.
The graph of g(x) is the graph of f(x) compressed vertically by a factor of
The graph of g(x) is the graph of f(x) shifted up 3 units.

Ответ:
Third Choice - The graph of g(x) is the graph of f(x) compressed vertically by a factor of 3
Step-by-step explanation:
x^2 is the the parent function, so it opens up with a normal compression.
Any number > (greater than) 1 as a coefficient of x will lead to a vertical compression (narrower parabola), while any number < (less than) 1 as a coefficient of x will lead to a vertical stretch (wider parabola).
So, 3x^2 would have to have to be a compressed parabola.
I hope this helps!
Ответ:
2x - 6 + x + 3 = 180
3x = 183
x = 61
