Answer:
f(x) = 2x+3
g(x) = 1/x^2
Step-by-step explanation:
There are many ways you can write the given expression as a function of a function. In general, you want to think about the operations that are performed on the variable, then consider which operations might be performed first, and what operations might be performed on the results of the first ones.
When the given expression is evaluated, you ...
• square the variable
• divide 2 by the result
• add 3 to that result
It is reasonable to divide this list into two parts, then make one function do one part of the list and the other function do the other part.
In our selection of f() and g() above, we have chosen to make g(x) be ...
• square the variable
• find the reciprocal of that result
and we have defined f(x) to be
• multiply that result by 2
• add 3.
__
You will note that multiplying the reciprocal by 2 is the same as dividing 2 by the result.
_____
Our f(x) and g(x) are ...
g(x) = 1/x^2
f(x) = 2x +3
X=4. Divide both side by -6 to get x by itself
Answer:
A
Step-by-step explanation:
You can eliminate B and D because it’s using 
, but the question is asking 
. So it’s either A or C. They are both written correctly, but out of the two, A is correct because just that x ≠ 
part of it is what makes it true.
The reason being is that the only thing that won’t make 
true is when the denominator equals 0, because anything divided by 0 is undefined. So, when you plug for x in the denominator you get: 
. The 
part just turns into 7, and 7 - 7 is 0. So you don’t want x to equal .
<u>So the answer is A:</u> 
, 
±
There you go my friend!
I hope you understand and that this helps with your question! :)
Answer:
scatter plot A: -0.90
scatter plot B: 0.89
scatter plot C: -0.76
scatter plot D: 0.55
Step-by-step explanation:
if the line is going down, it's negative and if it goes up it's positive. The closer the points are <em>the higher the number</em>.
HOPE THIS HELPS!!
The median is the middle number when the numbers are put in ascending order (lowest to highest)
1, 2, 3, 4, 4, 7
The middle numbers are 3 and 4. The number between 3 and 4 is thus the median - this number is 3.5
