**Question 1**. Decide whether or not the following equation is a circle. If so, find the center-radius form of its equation, and give its center and radius.

X2 + y2 – 4x + 6y = 12

·

** â€¨Question 2**. Evaluate the following function for the indicated values and expressions.

F(x) = 2x2 – 5x + 1

1 F(3)

2 F(-4)

3 F(3x)

4 F(2x + 3)

**â€¨â€¨Question 3**. Find the slope-intecept equation for the following lines.

1 The line passing through the points (1,9) and (-2,3)

2 The line passing through the point (1,2) and perpendicular to the line*y* = 3*x*-4.

**â€¨Question 4**. Without graphing, determine whether the equation has a graph that is symmetric with respect to the *x*-axis, the *y*-axis, the origin, or none of these.

2y = x2 + 1

**â€¨â€¨Question 5**. Suppose *f*(*x*) = 3*x* + 6 and *g*(*x*) = 2*x* - 1. Find each of the following:

1 (*f*+*g*)(2)

2 (*fg*)(2)
