a weight lifter can bench-press 145 pounds. She plans to increases the weight W(x) in pounds that she is lifting according to the function W (x)=145 (1.05), where x represents the number of training cycles she completes. How much will she bench-press after 5 training cycles?

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
