The x-intercepts of f(x) are common to those of g(x) .
<h3>What is x-intercept?</h3>
The x-intercept is the point on the coordinate at which a line, curve or plane intersect with the x-axis. The value of y is equal to zero at x-intercept.
For me, it helps to graph everything on the same xy coordinate system. Start with the given graph and plot the points shown in the table. You'll get what you see in the diagram below.
The blue point C in that diagram is on the red parabola. This point is the x intercept as this is where both graphs cross the x axis. Therefore, they have a common x intercept.
Choice 1 is not true due to choice 4 being true. We have f(x) = g(x) when x = 2, which is why f(x) > g(x) is not true for all x.
Choice 2 is not true. Point B is not on the parabola.
Choice 3 is not true. There is only one known intersection point between f(x) and g(x), and that is at the x intercept mentioned above. Of course there may be more intersections, but we don't have enough info to determine this.

Megan's solution isn't correct.
The first mistake: she subtracted 5x from the right-hand side of the equation, but added 5x to the left-hand side.
The second mistake: she divided the right-hand side of the equation by 11, but didn't divide the left-hand side.
The correct solution:
Answer:
B. Park users are more likely to be willing pay more to improve park.
Step-by-step explanation:
The sample is biased because it is only made up of people that patronize and use the park. They will be more willing to pay to improve the park because it satisfies and fulfills their needs.
This given sample is not representative of the poll as it is restricted to park users alone which are not the only tax payers in the area.
To have a more balanced representation, the whole population should be sampled irrespective of whether they are park users or not. This will give a fair representation.
Answer:
19.42 ft
Step-by-step explanation:
c^2 = a^2 + b^2
c^2 = 16^2 + 11^2
c^2 = 256 + 121
c = √377 = 19.416
