Answer:
The third answer- a reflection over the x axis then a reflection over the y axis
Answer:
B.
Step-by-step explanation:
Explanation:
Answer:
The solutions are 1 and 5.
Step-by-step explanation:
x2 − 6x + 5 = 0
Step 1: Write the related function.
x2 − 6x + 5 = 0
y = x2 − 6x + 5
Step 2: Graph the function.
Use a graphing calculator.
Step 3: Find the zeros.
The zeros are 1 and 5.
Answer:
Only C is a function
Step-by-step explanation:
To test whether a graph is a function you use the vertical line test.
If you can place a vertical line anywhere on the plane (in the domain of the "function" to be tested) and it intersects the curve at more than one point, the curve is not a function.
We see with A, wherever we put the vertical line it intersects twice.
With B, it intersects infinitely many times.
C is a function because wherever we put the vertical line, it only intersects once.
D is a function because it intersects twice providing we do not put it on the "tip" of the parabola.
The mathematical reasoning behind this is that a function must be well-defined, that is it must send every x-value to one specific y-value. There can be no confusion about where the function's input is going. If you look at graph B and I ask you what is f(3)? Is it 1? 2? 3? ... Who knows, it's not well-defined and so it's not a function. However if I ask you about C, whichever input value for x I give you, you can tell me to which y-value it gets mapped/sent to.
Answer:
the distance between (2,2) and (-3,1) is 
, which is about 5.10.
Step-by-step explanation:
on a graph it shows that:
rise/run = 1/5
