Solution
Let's solve the problem step by step.
a) Equation for :
-
Start with the function .
-
Vertical Compression by 14:
- A vertical compression by a factor of 14 multiplies the function by .
- The function becomes .
-
Shift Right by 1:
- Shifting the function to the right by 1 involves replacing with .
- The function becomes .
-
Shift Up by 2:
- Shifting the function up by 2 involves adding 2 to the function.
- The final function becomes .
So, the equation for is:
b) Slope of the Line:
- The slope of a linear function is the coefficient of .
- The slope of here is .
c) Vertical Intercept of the Line:
- The vertical intercept (also known as the y-intercept) occurs when .
- Substitute into :
Thus, the vertical intercept is .
Final Answers:
- a)
- b) The slope of this line is .
- c) The vertical intercept of this line is .
