Points

1. Find the slope-intercept equation of the straight line passing through

the point (1, −1) and parallel to the line y = 2x + 7.

2. Sketch the graph of f (x) = 3 + 2x+1. Clearly mark the asymptote(s)

and intercept(s).

5. For the function f (x) = − 2 x^2 + 4x + 1

(a) find the zeros, (b) find the vertex, (c) find the line of symmetry (d) find the intervals where f (x) increases or decreases.

6. Solve the inequality and write the solution using the interval

notation. Show your work.

(a) (x+2)(x−1) > 0

(b)

x^2 − 4

x + 2

8. Suppose you deposited $1000 into a savings account with the interest

rate 5%. (a) If the interest is compounded annually, find the formula A(t) for the amount of money in the account after t years. (b) If the interest is compounded continuously, find the formula A(t) for the amount of money in the account after t years. (c) If the interest is compounded continuously, after how many years you will have $2000 in this account? (Express your answer using logarithm(s), do not evaluate.)
