Function transformation involves changing the form of a function
- The transformation from f(x) to g(x) is a horizontal shift 3 units left, followed by a vertical stretch by a factor of 4
- The x and y intercepts are -0.67 and 1.91, respectively.
- The behavior of g(x) is that, g(x) approaches infinity, as x approaches infinity.
The functions are given as:
![\mathbf{f(x) = log3x}](https://tex.z-dn.net/?f=%5Cmathbf%7Bf%28x%29%20%3D%20log3x%7D)
![\mathbf{g(x) = 4log3(x+1)}](https://tex.z-dn.net/?f=%5Cmathbf%7Bg%28x%29%20%3D%204log3%28x%2B1%29%7D)
<u>(a) The transformation from f(x) to g(x)</u>
First, f(x) is shifted left by 1 unit.
The rule of this transformation is:
![\mathbf{(x,y) \to (x + 1,y)}](https://tex.z-dn.net/?f=%5Cmathbf%7B%28x%2Cy%29%20%5Cto%20%28x%20%2B%201%2Cy%29%7D)
So, we have:
![\mathbf{f'(x) = log3(x + 1)}](https://tex.z-dn.net/?f=%5Cmathbf%7Bf%27%28x%29%20%3D%20log3%28x%20%2B%201%29%7D)
Next. f'(x) is vertically stretched by a factor of 4.
The rule of this transformation is:
![\mathbf{(x,y) \to (x,4y)}](https://tex.z-dn.net/?f=%5Cmathbf%7B%28x%2Cy%29%20%5Cto%20%28x%2C4y%29%7D)
So, we have:
![\mathbf{g(x) = 4log3(x+1)}](https://tex.z-dn.net/?f=%5Cmathbf%7Bg%28x%29%20%3D%204log3%28x%2B1%29%7D)
Hence, the transformation from f(x) to g(x) is a horizontal shift 3 units left, followed by a vertical stretch by a factor of 4
<u>(b) Sketch of g(x)</u>
See attachment
<u>(c) Asymptotes</u>
The graphs of g(x) have no asymptote
<u>(d) The intercepts, and the behavior of f(x)</u>
The graph crosses the x-axis at x =-0.67, and it crosses the y-axis at y = 1.91
Hence, the x and y intercepts are -0.67 and 1.91, respectively.
The behavior of g(x) is that, g(x) approaches infinity, as x approaches infinity.
We know this because, the value of the function increases as x increases
