Back

n = 1/2

Front

Determine if this is a function: { (1, 2), (2, 3), (1, 4) }

Back

Not a Function

Front

Is the relation {(1, 2), (2, 3), (3, 4)} a function?

Back

Yes

Front

Solve for x: 4(1-x) + 3x = -2(x+1)

Back

x = -6

Front

Is the sequence geometric? If so, identify the common ratio: 6, 12, 24, 48

Back

yes, 2

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What is the common ratio in a geometric sequence?

Back

The factor by which each term is multiplied to get the next term.

Front

Solve for n: 2n + 3 = 11

Back

n = 4

Front

What is the formula for the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1) for points (x1, y1) and (x2, y2).

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / (2a) for ax² + bx + c = 0.
