Math Problem Statement
Determine each feature of the graph of the given function. f, of, x, equals, start fraction, 5, divided by, 2, x, minus, 3, end fraction f(x)= 2x−3 5
Answer
Horizontal Asymptote: y, equalsy=
Vertical Asymptote: x, equalsx=
x-Intercept: left parenthesis( comma, 0, right parenthesis,0) y-Intercept: left parenthesis, 0, comma(0, right parenthesis) Hole: left parenthesis( , right parenthesis)
Solution
We are tasked with analyzing the function:
Features of the graph:
1. Horizontal Asymptote:
The horizontal asymptote depends on the degrees of the numerator and denominator.
- The numerator (constant: 5) is of degree 0.
- The denominator () is of degree 1.
Since the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is:
2. Vertical Asymptote:
The vertical asymptote occurs where the denominator equals zero.
Thus, the vertical asymptote is:
3. x-Intercept:
The -intercept occurs when , which means setting the numerator equal to zero:
Since this is never true, there is no -intercept.
4. y-Intercept:
The -intercept occurs when :
Thus, the -intercept is:
5. Hole:
A hole occurs if there are common factors in the numerator and denominator that cancel out. Since the numerator is a constant and the denominator does not share a common factor, there are no holes in the graph.
Final Answer:
- Horizontal Asymptote:
- Vertical Asymptote:
- x-Intercept: None
- y-Intercept:
- Hole: None
