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:

f(x)=52x3f(x) = \frac{5}{2x - 3}

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 (2x32x - 3) is of degree 1.

Since the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is:

y=0y = 0

2. Vertical Asymptote:

The vertical asymptote occurs where the denominator equals zero.

2x3=0    x=322x - 3 = 0 \quad \implies \quad x = \frac{3}{2}

Thus, the vertical asymptote is:

x=32x = \frac{3}{2}

3. x-Intercept:

The xx-intercept occurs when f(x)=0f(x) = 0, which means setting the numerator equal to zero:

5=05 = 0

Since this is never true, there is no xx-intercept.

4. y-Intercept:

The yy-intercept occurs when x=0x = 0:

f(0)=52(0)3=53=53f(0) = \frac{5}{2(0) - 3} = \frac{5}{-3} = -\frac{5}{3}

Thus, the yy-intercept is:

(0,53)(0, -\frac{5}{3})

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: y=0y = 0
  • Vertical Asymptote: x=32x = \frac{3}{2}
  • x-Intercept: None
  • y-Intercept: (0,53)(0, -\frac{5}{3})
  • Hole: None
