Solution

Let's solve the problem step by step.

a) Equation for g(x)g(x):

  1. Start with the function f(x)=xf(x) = x.

  2. Vertical Compression by 14:

    • A vertical compression by a factor of 14 multiplies the function by 114\frac{1}{14}.
    • The function becomes 114x\frac{1}{14}x.
  3. Shift Right by 1:

    • Shifting the function to the right by 1 involves replacing xx with (x1)(x - 1).
    • The function becomes 114(x1)\frac{1}{14}(x - 1).
  4. Shift Up by 2:

    • Shifting the function up by 2 involves adding 2 to the function.
    • The final function becomes g(x)=114(x1)+2g(x) = \frac{1}{14}(x - 1) + 2.

So, the equation for g(x)g(x) is: g(x)=114(x1)+2g(x) = \frac{1}{14}(x - 1) + 2

b) Slope of the Line:

  • The slope of a linear function g(x)=mx+bg(x) = mx + b is the coefficient of xx.
  • The slope of g(x)g(x) here is 114\frac{1}{14}.

c) Vertical Intercept of the Line:

  • The vertical intercept (also known as the y-intercept) occurs when x=0x = 0.
  • Substitute x=0x = 0 into g(x)=114(x1)+2g(x) = \frac{1}{14}(x - 1) + 2:

g(0)=114(01)+2=114+2=1+2814=2714g(0) = \frac{1}{14}(0 - 1) + 2 = \frac{-1}{14} + 2 = \frac{-1 + 28}{14} = \frac{27}{14}

Thus, the vertical intercept is 2714\frac{27}{14}.

Final Answers:

  • a) g(x)=114(x1)+2g(x) = \frac{1}{14}(x - 1) + 2
  • b) The slope of this line is 114\frac{1}{14}.
  • c) The vertical intercept of this line is 2714\frac{27}{14}.

  1. What happens to the slope if there is a horizontal stretch instead of a compression?
  2. How would the equation change if the function was shifted left instead of right?
  3. What if the function f(x)f(x) was originally f(x)=2x+3f(x) = 2x + 3?

Tip: Always apply transformations in the order: stretches/compressions, reflections, translations (shifts) for consistency.
