SECTION 2.1

Exercise 4

Yes this is a solution since the coordinates 2,-1 satisfy the equation.

Exercise 6

No this is not a solution because the coordinates (1,-1) does not satisfy the equation.

Exercise 16 X intercept 1

Y intercept doesn't exist because it will never cross the Y axis

Exercise 18 X intercept 5Y intercept 5/-2

First set y 0 to solve for X Intercept

Next, set x 0 and solve the equation to find the Y intercept

Exercise 26

Y-intercept 0; X-intercepts are -2 and 2/3

Exercise 30 Sketch the Graph X and Y Intercept 0

Exercise 40 Y intercept is 3; X intercepts are 3

Parabola touching on the points listed.
