College Algebra Semester 1 Review

Front

Identify the zeros of the polynomial function: x^2 + 3x - 10

Back

The zeros are x = 2 and x = -5.

Front

What does the graph of a constant function y = c look like?

Back

It is a horizontal line at y = c.

Front

What is the solution to the system of equations: 2x + 3y = 6 and x - y = 1?

Back

The solution is (3, 0).

Front

Factor the quadratic expression: x^2 - 5x + 6

Back

(x - 2)(x - 3) is the factored form.

Front

What does it mean for two lines to intersect on a graph?

Back

It means they have a common solution (x, y) where both equations are satisfied.

Front

Identify the zeros of the polynomial function: x^2 - 4

Back

The zeros are x = 2 and x = -2.

Front

What is the graph of y = mx + b?

Back

It is a straight line with slope m and y-intercept b.

Front

Solve for x: 3x - 9 = 0

Back

x = 3.

Front

What is the vertex of the parabola represented by the equation y = x^2 - 4x + 4?

Back

The vertex is at the point (2, 0).

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / (2a).
