Review 3.4-3.7

Front

Evaluate f(-2) if f(x) = x + 3

Back

f(-2) = -2 + 3 = 1

Front

Find the missing OUTPUT value for the function: f(x) = 2x + 1 when x = -10

Back

OUTPUT = -19

Front

Find the zero of the function: -2x + 6 = 0

Back

x = 3

Front

What happens to a person parachuting from an airplane when they open their chute?

Back

They slow down and land on the ground.

Front

Find the zero(s) of the function: y = 2x^2 - 8

Back

x = -2, 2

Front

What is a function?

Back

A relation that assigns exactly one output for each input.

Front

Define the term 'zero of a function'.

Back

The value of x for which f(x) = 0.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean for a function to be linear?

Back

It means the graph of the function is a straight line.
