3.Let \(f(x) = \frac{2x^2 - 50}{x^2 + 2x - 15}.\)Find the values of k for which the equation x=k is a vertical asymptote of the graph of y=f(x) Enter all such values, separated by commas.
4. Enter the equation of the horizontal asymptote of the graph of \(f(x) = \frac{7x^3 - x^2 - 2}{3x^5 + 14x^2 + 33x + 8}.\)
+174 Problem 1:
The function simplifies to f(x) = 2(x + 5)/(x + 3). You can then see that the function is not defined for x = -3.
+174 Problem 2:
We can rewrite the equation in the desired form by multiplying both sides by the denominator of the original equation, (x+7).
Steps to solve:
Multiply both sides by (x+7): y * (x + 7) = (x - 3)
Substitute y with its definition: (x - 3)/(x + 7) * (x + 7) = (x - 3)
Simplify: x - 3 = (x - 3)
Now, we can see that the equation holds true for any value of x (as long as x ≠ -7 to avoid dividing by zero in the original equation). This means we can set the right side to any constant value (c) to maintain the truth of the equation.
However, to achieve the desired form (x + a)(y + b) = c, we should choose c = 0 (since the right side is already 0).
Therefore, a = 0, b = -7 (as y is replaced by (x - 3)/(x + 7)), and c = 0.
'
The answer in the form a, b, c is: 0, -7, 0
