Alg 2 Semester 2 Review Day 1 Extra Practice

Front

Solve: 14y + 5 = 8y - 1

Back

y = -1

Front

Solve the quadratic equation: x^2 - 2x - 15 = 0

Back

x = 5, x = -3

Front

What is the average rate of change of f(x) = 2x^2 + 12x + 16 on the interval [-3, -2]?

Back

2

Front

Solve the system of equations: 3x + 7y = 23 and -3x - 7y = -17

Back

No solution

Front

What are the solutions to the function?

Back

-4, 2

Front

What is the definition of a quadratic equation?

Back

A polynomial equation of the form ax^2 + bx + c = 0, where a ≠ 0.

Front

What is the quadratic formula?

Back

x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}

Front

Define the term 'average rate of change'.

Back

The average rate of change of a function over an interval [a, b] is given by \frac{{f(b) - f(a)}}{{b - a}}.

Front

What does it mean if a system of equations has no solution?

Back

It means the lines represented by the equations are parallel and do not intersect.

Front

What is the vertex form of a quadratic function?

Back

f(x) = a(x - h)^2 + k, where (h, k) is the vertex.
