Q2 CFA Review

Front

Identify where the function is decreasing.

Back

The function is decreasing for x < -4 and x > 1.

Front

Which of these represents point-slope form of a linear equation?

Back

y - y₁ = m(x - x₁)

Front

When is this function increasing?

Back

The function is increasing for -2.5 < x < 2.5.

Front

Write the equation of the line with slope = -4, passing through (-1, 5).

Back

y - 5 = -4(x + 1)

Front

This graph is: Increasing, Decreasing, Both increasing and decreasing, Neither increasing nor decreasing?

Back

Decreasing.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.

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 increasing?

Back

A function is increasing if, as x increases, the value of f(x) also increases.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as x increases, the value of f(x) decreases.
