Math Problem Statement
Find the x-intercept(s) and y -intercept(s) of the graph of the following. y=4x+3/x^2+4 If there is more than one answer, separate them with commas. Click on "None" if applicable.
Solution
To find the x-intercepts and y-intercepts of the function , we need to follow these steps:
1. Find the y-intercept:
The y-intercept occurs when . Substituting into the equation:
Thus, the y-intercept is .
2. Find the x-intercept(s):
The x-intercepts occur when . Set the function equal to zero and solve for :
For a fraction to be zero, the numerator must be zero. So, solve:
Thus, the x-intercept is .
Final answer:
- x-intercept:
- y-intercept:
