Answer:
B. The graph of g(x) is narrower than the graph of f(x)
D.The graph g(x) is 8 units above the graph of f(x)
check the image given below.
- The blue line refers to graph g(x)
- The red line refers to graph f(x)
This is the formula to solve for the vertex.
Example Question:
Find the vertex of y = -0.5x^2 + 100x
-b/2a = -100/2(-0.5) = -100/-1 = 100
The x coordinate of the vertex is 100.
Best of Luck!
P.S. this is 1000th question i've answered :)
