The graph of a quadratic function intersects the x-axis at -3 and 5.
What is a possible equation for f(x) ?
Write a system of equations
In a basketball game, Marlene made 16 field goals. Each of the field goals were worth either 2 points or 3 points, and Marlene scored a total of 39 points from field goals.
Let x represent the number of 2-point field goals and y represent the number of 3 point field goals. Write a system of
equations, in terms of x and y, to model the situation.
Which expression is equivalent to (2x² + 3)(x + 4) ?
A.) 2x³ + 12
B.) 2x² + 11x + 12
C.) 2x³ + 6x² + 4x + 12
D.) 2x³ + 8x² + 3x + 12

The figure shows the graphs of the functions y = f(x) and y = g(x). The four indicated points all have integer coefficients.
If g(x) = k(f(x), what is the value of k?
What factorization can be used to reveal the zeros of f(x) = -12x² - 11x + 15 ?
A.) f(x) = -x(12x + 11) + 15
B.) f(x) = (-4x + 3)(3x + 5)
C.) f(x) = -(4x + 3)(3x + 5)
D.) f(x) = (4x + 3)(-3x + 5)
