Math Problem Statement

f(x) = 2^(x - 4) + 10

Solution

The function given in the image is:

f(x)=2(x4)+10f(x) = 2^{(x - 4)} + 10

This is an exponential function where the base is 2 and the exponent is x4x - 4, with a vertical shift of +10.

Key points about the function:

  1. Exponential Growth: The function represents exponential growth, since the base of the exponent (2) is greater than 1.
  2. Horizontal Shift: The term x4x - 4 means that the graph of the function is shifted 4 units to the right.
  3. Vertical Shift: The constant +10 means the graph is shifted 10 units upwards.
  4. Asymptote: The horizontal asymptote of this function is y=10y = 10, because as xx \to -\infty, 2(x4)02^{(x-4)} \to 0, and the function approaches 10.
  5. Intercept: To find the y-intercept, substitute x=0x = 0 into the function.

Calculating the y-intercept:

f(0)=2(04)+10=24+10=116+10=10.0625f(0) = 2^{(0 - 4)} + 10 = 2^{-4} + 10 = \frac{1}{16} + 10 = 10.0625 So the y-intercept is approximately 10.062510.0625.
