Suppose the number is x, its reciprocal is 1/x
x+1/x=13/6
(x^2+1)/x=13/6
6(x^2+1)=13x
6x^2-13x+6=0
(3x-2)(2x-3)=0
x=2/3 or x=3/2
27-9r
explaintion:
3•9+3•-3r
27+3•-3r=
27-9r
The inverse is h squared -1 (x) = 2/5x -8/5
Multiply the second fraction by two; which gets you 5/10 + 2/10 = 7/10
Consider the function First, factor it:
The x-intercepts are at points
1. From the attached graph you can see that
- function is positive for
- function is negative for
2. Since
the function is neither even nor odd.
3. The domain is the range is
