Answer:
The function g(x) = (x + 1)² is represented by the graph Y
Step-by-step explanation:
The question presents the graph of the function x² above
Therefore, for a function f(x) = x² at x = 0 y = 0
For function g(x) = (x + 1)² when x = 0 g(x) = 1 Satisfied by graph W and Y
Also we have g(x) = (x + 1)² = x² + 2·x + 1 or g(x) = f(x) + 2·x + 1
We find the minimum of the graph by differentiating and equating to zero as follows;
Therefor, the minimum is at x = -1 satisfied by only graph Y
Hence the graph that represents the function g(x) = (x + 1)² is the graph Y.
Answer:
Increasing by 40%
Step-by-step explanation:
This is a exponentional function. The format for this type of function is a(b)^x. So "a" is your initial value, and "b" is the rate. Now let's think to ourselves what times what is still equal to the same thing? That is 1. But in our question, we have 1.4. So we are increasing by 0.4, or 40%.
I'm not at my desk and can't check it out right now.
But I think you should try 10 and -42 .
Nothing else is given, so for the two triangles to be congruent, the only possible proof is the ASA theorem.
first pairs of angles: 2x+7=x+21 => x=14
second pairs of angles: 8y-4=4y+28 =>y=8
The two triangles share the same side PR
Based on the Angle-Side-Angle Triangle Congruence theorem, these two triangles are congruent with x=14, y=8
(2x+7) +(8y-4) +Q=180 =>85
You're 42. 42-21=21 and 21x2=42.
