Answer:
see below
Step-by-step explanation:
f(x) +k is a vertical shift
+k shifts the graph up k units
-k will shift the graph down k units
f(x) -2 will shift the graph of f(x) down 2 units

Answer:
Your question is sideways rotate so I can help easier
Step-by-step explanation:
I will explain how to get the solution using the text and look at the image as well as I’m using it to explain my process.
Step 1: Write the equation for slope-intercept form which is y=mx + b
Step 2: FIND SLOPE. M means slope in mathematics and the formula for that is rise divided by run. Which actually means y2 - y 1 divided by x2 - x1. If you are wondering what those are, they are points in the graph. It doesn’t matter which point you choose but you’ll see which ones I chose in the image. Follow the steps there
Step 3: FIND Y INTERCEPT: this step is easy because you are provided with a graph so you don’t have to find the y intercept algebraically. The y intercept is where the graph touch’s the y axis. In your case, it is at -4.
Step 4: CREATE THE EQUATION.
Refer to step one and re write the equation for slope intercept form: y=mx + b. Replace m with -2 and b with -4. So your equation looks like this: y= -2x -4
Answer:
diameter = 16cm, circumference ≈ 50.27
Step-by-step explanation:
The radius is 8 centimeters, so the diameter should be twice of that because the radius is the distance from the middle of the circle to the edge while the diameter is from edge to edge passing through the middle of the circle. Therefore,
8 · 2 = 16cm
The equation for the circumference of a circle is 2πr. In this case, because nothing else is specified about π, we use 3.14. So,
2 · 3.14 · 8 ≈ 50.27
Hope this helped! Have a great day. ^^
