## CAT03 quant doubts

Can some one tell me the answers of following CAT03 questions

10. When the curves y = log_{10} x and y = x^{-1} are drawn in the x-y plane, how many times do they intersect for values x > 1 ?

- a. Never
- b. Once
- c. Twice
- d. More than twice.
- e.Not Attempted

16. The number of non-negative real roots of 2^{x} - x - 1 = 0 equals

- a. 0
- b. 1
- c. 2
- d. 3
- e.Not Attempted

## 1. one point if you plot

1. one point if you plot them . well you exactly need to plot them , knowing the shap and limits of the curve would suffive

2. 2 points , again plot 2^x and x+1
