Math Problem Statement

Let f(x) = 2sqrt(x). If g(x) is the graph of f(x) shifted up 6 units and right 1 unit, write a formula for g(x).

Solution

We are given the function f(x)=2xf(x) = 2\sqrt{x}, and we need to find a new function g(x)g(x) based on shifts to the graph of f(x)f(x).

The graph of f(x)f(x) is: f(x)=2xf(x) = 2\sqrt{x}

Now, we are told that g(x)g(x) is obtained by shifting f(x)f(x) up by 6 units and right by 1 unit.

Step 1: Shifting Right by 1 Unit

Shifting a graph to the right by 1 unit means replacing xx with x1x - 1. So, the function becomes: f(x1)=2x1f(x - 1) = 2\sqrt{x - 1}

Step 2: Shifting Up by 6 Units

Shifting a graph up by 6 units means adding 6 to the function. Therefore, we add 6 to the previous expression: g(x)=2x1+6g(x) = 2\sqrt{x - 1} + 6

Final Answer:

g(x)=2x1+6g(x) = 2\sqrt{x - 1} + 6

Let me know if you would like further details or have any questions.

Here are five related questions for further practice:

  1. What is the effect of shifting a graph down by 4 units instead of up?
  2. How would the formula change if the graph was shifted left by 2 units?
  3. What happens to the graph of g(x)g(x) if it is reflected over the x-axis?
  4. How would you shift f(x)f(x) left by 3 units and down by 5 units?
  5. Can you describe the transformations that occur if f(x)f(x) is scaled vertically by a factor of 3?

Tip: To shift a graph horizontally, you change the input xx by adding or subtracting inside the function, while vertical shifts involve adding or subtracting directly from the function itself.
