Sample 3rd Midterm
Skip to 5, 6
Graph y = 2x - 3.
What is the slope of the line joining (2, 3) and (4, 1)?
3. What is the equation of the line in #2?
that you after 3 months you have $350 in your account and after 7
months you have $650.
Let x denote the number of months the and let y denote the amount
of money in the account. Find a linear equation which will predict
how much money you will have in the account as a function of the
number of months
Graph this function.
Use this function to determine how much money you will have after
y = f(x) = x2 + 2x - 8
x2 + 2x - 8> 0
What is the y - intercept?
What are the roots?
What are the coordinates of the vertex?
Write the equation in standard or vertex form.
Solve for x
What is the y-intercept?
What are the roots or x-intercepts?
Where are the vertical asymptotes?
Are there any horizontal asymptotes and if so where are they?
Solve for x.
In 7 and 8, solve for x and check
