Math Problem Statement

y = x-1/(x+3)(x-2) find the x and y intercept

Solution

To find the xx-intercept and yy-intercept for the equation y=x1(x+3)(x2)y = \frac{x-1}{(x+3)(x-2)}, follow these steps:

1. Finding the yy-intercept:

The yy-intercept occurs when x=0x = 0. Substituting x=0x = 0 into the equation:

y=01(0+3)(02)=1(3)(2)=16=16y = \frac{0 - 1}{(0 + 3)(0 - 2)} = \frac{-1}{(3)(-2)} = \frac{-1}{-6} = \frac{1}{6}

So, the yy-intercept is at: (0,16)(0, \frac{1}{6})

2. Finding the xx-intercept:

The xx-intercept occurs when y=0y = 0. This means we need to solve for xx when y=0y = 0.

0=x1(x+3)(x2)0 = \frac{x-1}{(x+3)(x-2)}

For a fraction to be zero, the numerator must be zero. So, solve the numerator:

x1=0    x=1x - 1 = 0 \implies x = 1

Thus, the xx-intercept is at: (1,0)(1, 0)

Conclusion:

  • xx-intercept: (1,0)(1, 0)
  • yy-intercept: (0,16)(0, \frac{1}{6})
