4. Examples
1) 2) 3) 4)

5. Find the intercepts and sketch

6. Find the intersection of the graphs

7. Equation of Line Point-slope form y – y1 = m (x – x1)
Example: Find the equation of a line that has a slope of 3 and passes through the point (1, -2)

8. Find the equation of the line that passes through the points (-3, 6) and (1, 2)
2) Parallel to the line in #1 and passing through the point ( -1, 4)
3) Perpendicular to the line in #1 and passing through the point (-1,4)

9. Finding the Domain Domain is all x values for which f(x) exists
Range is all possible y values
Example: Find the domain and range for each below
a) f(x) = √(5 – x2)
b) g(x) = (x2 – x – 6)/(x2 – x)

10. Evaluating Functions
Functions can be evaluated at any point in their domain
Example: For f(x) = 3x2 – x + 2, find:
f(0)
f(-1)
f(2a)
f(x + h)
2f(x)
