What is the period of the function F(x) = -4sec (1/2 x)

serg [7]

Answer:

A) 4π

Step-by-step explanation:

The period of a secant function, f(x)=a*sec(bx+c)+d, is defined as 2π/|b| where b is the distance of the period. Since we know b=1/2 given by the function, then the period is 2π/|1/2|=2π/(1/2)=2π(2/1)=4π.

Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

Step 1: Define

Identify points from graph.

Point (20, 0)

Point (100, 40)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{40 - 0}{100 - 20}$
[Order of Operations] Simplify: $\displaystyle m = \frac{40}{80}$
Simplify: $\displaystyle m = \frac{1}{2}$
