Given the rational function f(x)=2x+6/x-3, Answer the following questions.
AysviL [449]

Answer:

  1. A rational function is any function which can be written as the ratio of two polynomial functions, where the polynomial in the denominator is not equal to zero. The domain of f(x)=P(x)Q(x) f ( x ) = P ( x ) Q ( x ) is the set of all points x for which the denominator Q(x) is not zero
  2. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y
  3. The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
  4. In mathematics, a zero of a real-, complex-, or generally vector-valued function f, is a member x of the domain of f such that f(x) vanishes at x; that is, the function f attains the value of 0 at x, or equivalently, x is the solution to the equation f(x) = 0.

#19<br> The distance between the points (4, 1) and (9, 1) is
kirill115 [55]

Hello!

Given the two points, (x_{1}, y_{1}) and (x_{2}, y_{2}), and to find the distance between these two points is found by using the formula:

d = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}

(x_{1}, y_{1}) is assigned to one the points, in this case, is (4, 1).

(x_{2}, y_{2}) is assigned to other point, which is (9, 1).

Then, plug in these values into the formula and solve.

d = \sqrt{(9-4)^{2}-(1-1)^{2}}

d = \sqrt{5^{2}-0^{2}}

d = \sqrt{25}

d = 5

Therefore, the distance between the two points is 5.
