Math Problem Statement
What are the x- and y-intercepts of the equation?
y=log(3x+4)+2
Round only the final answers to the nearest hundredth.
Enter your answers in the boxes.
x-intercept = y-intercept =
Solution
To find the intercepts of the equation , we proceed as follows:
1. Finding the y-intercept:
The y-intercept occurs when .
Substitute into the equation:
Now calculate using base 10:
So,
Rounded to the nearest hundredth, the y-intercept is:
2. Finding the x-intercept:
The x-intercept occurs when .
Set in the equation:
To isolate the logarithmic term, subtract 2 from both sides:
Convert the logarithmic equation to its exponential form:
Now solve for :
Rounded to the nearest hundredth, the x-intercept is:
Final Answers:
- x-intercept
- y-intercept
