Okay, let's first establish some ground rules.
1) Whenever something is subtracted or added to x directly, it is a horizontal transformation. In other words, the function is shifted either left or right. Subtraction is right, addition is left.
EX: In y = (x - 4)^2, the function x^2 is moved 4 units to the right.
2) Whenever something is subtracted or added to the whole function, it is a vertical transformation. In other words, the function is shifted either up or down. Subtraction is down, addition is up.
EX: In y = x^2 + 4, the function x^2 is moved 4 units up.
Here, the function |x| is moved <em>4 units to the right </em>and <em>3 units down. </em>So, the vertex will be at point (4, -3). Being more technical:
m = -1 if -∞ < x ≤ 4 and m = 1 if 4 < x < ∞
Hope this helps, let me know if I messed up!
Answer:
m=
Step-by-step explanation:
Gladly!
To find the slope, we need to find the change between <em>point a</em> and <em>point b</em>
With the difference between x1 and x2 being 4, and the difference between y1 and y2 being 1, we get a fraction that looks like this,
This right here is the slope of the line. Hope this helps!
Answer: A: He payed 3 dollars in sales tax B: He payed 27.59 for his ticket
Step-by-step explanation:
A: 42.99 + 7% = 45.99 - 42.99 + 3
B: 42.99 - 40% = 24.79 + 7% = 27.59
