### Subject: Pre-Calculus

How do you graph the square root function: y = sqrt(x-5) +2

First use a parent function and parent points: y = sqrt(x). Parent points can be (0,0), (1,1), (4,2), and (9,3). Use these parent points to solve for the actual points. From the equation, all x values will be become (x+5) and all y values will become (y + 2). Final points are (5,2) , (6,3), (9, 4), and (14, 5).

### Subject: Biology

How does DNA and RNA base pair?

For DNA, adenine and thymine base pair with 2 hydrogen bonds between and guanine and cytosine base pair with 3 hydrogen bonds between. For RNA adenine and uracil base pair with 2 hydrogen bonds between and guanine and cytosine base pair with 3 hydrogen bonds between.

### Subject: Algebra

How do you simplify the following expression: (x-2)(3x+2)?

For expressions like this, utilize the FOILing technique. Multiply the first terms of each parenthesis set (x and 3x), then multiply the outer terms of each parenthesis set (x and 2), then the inner terms (-2 and 3x), and finally the last terms (-2 and 2). Then add or subtract common terms.
