Question

Which of the following is the graph of function g such that g(x) = 3f(x) + 4?

Answer 1

Answer: D for plato users

Answer 2

Look for a graph whose y-coordinate have been moved up 4 units and its function has been vertically stretched by a factor of 3.

Explanation:

Function transformations have several rules that define them:

• Adding or subtracting to the function will move it's y coordinates up.
• Adding or subtracting inside the function will move it's x-coordinates left or right.
• Multiplying by a number greater than 1 to the function will strtetch it.
• Multiplying by a number less than 1 will compress the function.

The graph of g will be the graph of f(x) moved 4 units up and stretched by a factor of 3. It depends on what f(x) is to begin with to see the exact look.
