In the following exercises, (a) find the center-radius form of the equation of each circle described, and (b) graph it. See Examples 5 and 6. center (0, 0), radius 6

In the following exercises, (a) find the center-radius form of the equation of each circle described, and (b) graph it. See Examples 5 and 6. center (√2, √2), radius √2

For each equation, (a) give a table with at least three ordered pairs that are solutions, and (b) graph the equation. See Examples 3 and 4.

2x + 3y = 5

Concept Check Graph the points on a coordinate system and identify the quadrant or axis for each point. (3, 2)

For each equation, (a) give a table with at least three ordered pairs that are solutions, and (b) graph the equation. See Examples 3 and 4. y = ½ x - 2

Concept Check Plot each point, and then plot the points that are symmetric to the given point with point with respect to the (a) x-axis (-4, -2)

For each equation, (a) give a table with at least three ordered pairs that are solutions, and (b) graph the equation. See Examples 3 and 4.

y = x³

Concept Check Plot each point, and then plot the points that are symmetric to the given point with point with respect to the (c) origin. (5, -3)

Graph each function. See Examples 6–8. h(x) = 2x² - 1

Graph each function. See Examples 6–8. g(x) = (x - 4)²

Determine whether each function is even, odd, or neither. See Example 5. 1 ƒ(x) = x + —— x⁵

Rewrite each statement with > so that it uses < instead. Rewrite each statement with < so that it uses >. See Example 6. 6 > 2

Concept Check Graph the points on a coordinate system and identify the quadrant or axis for each point. (4.5, 7)

In the following exercises, (a) find the center-radius form of the equation of each circle described, and (b) graph it. See Examples 5 and 6.

center (0, 4), radius 4

Rewrite each statement with > so that it uses < instead. Rewrite each statement with < so that it uses >. -9 < 4
