The graph of f(x) = 2x. The graph of g(x) = ()x is the graph of f(x) = 2x reflected over the y-axis. Which graph represents g(x)
2 answers:
Reflect across y axis means that you replace x with -x
f(-x)=2(-x)=-2x
g(x)=-2x
de graph is the one that passes through (0,0) and (1,-2) and -1,2)
For this case we have transformation of functions:
Reflection is the mirror image of a figure. It can also be defined as the turning of points and graphs around the axes.
So, we have:
To graph , the graph of is reflected on the y-axis. (Horizontal reflection)
If , to obtain g (x) as a horizontal reflection, we evaluate
Thus:

Step-by-step explanation:
They have 121 apples all together. 110+5=115, 115+6=121
Your answer will be: 3.30549069 x 10x10x10x10x10x10x10x10x10x10x10x10x10
<span>1. Quizzes (10% each):
60 x 10/100 = 6
69 x 10/100 = 6.9
68 x 10/100 = 6.8
2. Exam (70%)
65 x 70/100 = 45.5
Add them all up now:
6 + 6.9 + 6.8 + 45.5 = 65.2
Therefore, answer is </span><span>65.2</span>
