Answer:

Step-by-step explanation:

A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Example. f(x)=x+7.

Answer:

3

Step-by-step explanation:

This is very simple.

f(x) means the function of x.

The question means,

"What is the function result if 2 was x"

The table does not show how it works, but it gives the result directly.

In the table, in the "x" column, there is a 2.

In the "f(x)" column, there is a 3 next to the number 2.

A rectangle is drawn on a coordinate plane. Three vertices of the rectangle are points
igomit [66]

Answer:

4

Step-by-step explanation:

The distance from B to C is the same as the distance from A to D. Points B and C will both have the same x-value, as do points A and D. Points B and C will have the same difference in y-values (2 -(-2) = 4) that points A and D have.

The distance from B to C is 4 units.
