The function g is the transformation of f(x) = IxI given by g(x) = -f(x + 15) – 7. Find the value of f(x) and g(x) for x = -11?

Selena needs at least 22 subway rides for the month. She has two options for buying subways cards. Write a function that represents the situation
which situation is correct when Selena has a certain number of rides?
Statement 1: If she has 22 rides for the month then the total cost is $ 30.5
Statement 2: If she has 26 rides for the month then the total cost is $ 25

What function g describes the graph of f after the given transformation?
f(x) = IxI + 1; translated 3 units down and 2 units left.

Remember how a function changes in different directions.

Write a function for the graph.

A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

Find the vertex of the function. f(x) = Ix + 7I – 2

What function has the same graph as f(x) = 4Ix – 2I + 2?

A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

The function g is the transformation of f(x) = IxI given by g(x) = -f(x + 15) – 7. Find the value of f(x) and g(x) for x = -15?

Observe the problem carefully and notice where we have to use just x and where we have to use a function of x.
