# Evaluating and Graphing Functions and Trigonometry Word Problems

(1) For the function: (see attached)

a) Give the y values for x = -1, 0, 1, 2, 3, 4.

b) Using these points, draw a curve.

(2) For the equation , perform the following:

(a) Solve for all values of x that satisfies the equation.

(b) Graph the functions y = x and on the same graph (by plotting points if necessary). Show the points of intersection of these two graphs.

Graph:

Points of intersection:

(3) A right triangle is a triangle with one angle measuring 90°. In a right triangle, the lengths of the sides are related by the Pythagorean Theorem, , where c is the length of the hypotenuse (the side opposite the 90° angle). Find the length of the hypotenuse when the other two sides' measurements are 6 feet and 8 feet.

(4) Suppose you travel north for 65 kilometers then travel east 75 kilometers. How far are you from your starting point?

(5) The volume of a cube is given by V = s3, where s is the length of a side. Find the length of a side of a cube if the Volume is 1000 cm3.
