Question:

Find the limit of 2/x, as x approaches infinity.

Julie L.

SInce 2 is a constant, we can bring it out of the limit. We arrive with 2 (limit of 1/x, as x approaches infinity). We can observe that as x approaches infinity, the value of 1/x becomes smaller and smaller, approaching 0. Therefore the limit of 1/x as x approaches infinity is 0, 2 multiplied to 0 is 0. Therefore, limit of 2/x, as x approaches infinity is 0.

Question:

Find two consecutive numbers if the sum of the two numbers is 2 more than three times the smaller number.

Julie L.

Let x be the smaller number and x+2 be the larger number. The sum of the two numbers, which is x+(x+2) is said to be 3x+2. Equating the two expressions, x+(x+2)=3x+2. Isolation the variable x, we arrive with x= 0. Therefore, the two consecutive numbers are 0 and 2.
