Can someone check my answer please? Find the corresponding y values for x = -2,-1,0,1,2,3 if y = x^-x-2. My answers are under Y.
X Y
-2 -4
-1 -2
0 -2
1 0
2 4
3 10
You have already posted this question three times. This is not necessary.
I have asked for clarification of your equation. I cannot help you until you provide that information.
I tried it won't let my the equation is x = -2, -1, 0, 1, 2, 3 if y = x^-x-2
y = x^-x-2
Is this y equals x raised to the (-x) power or y equals x raised to the (-x-2) power or something else?
y = x(squared)x-2
This notation is still illogical to me. You should either learn to type equations on the computer, or you could simply write the equation in words as you would say it.
To check your answers, we need to substitute the given x-values into the equation y = x^(-x-2) and calculate the corresponding y-values.
Let's go through each x-value one by one:
For x = -2:
Substituting x = -2 into the equation, we get:
y = (-2)^(-(-2)-2)
y = (-2)^(-2+2)
y = (-2)^0
y = 1
For x = -1:
Substituting x = -1 into the equation, we get:
y = (-1)^(-(-1)-2)
y = (-1)^(-1+2)
y = (-1)^1
y = -1
For x = 0:
Substituting x = 0 into the equation, we get:
y = (0)^(-0-2)
y = (0)^(-2)
y = Undefined (since any number raised to the power of -2 is undefined)
For x = 1:
Substituting x = 1 into the equation, we get:
y = (1)^(-1-2)
y = (1)^(-3)
y = 1
For x = 2:
Substituting x = 2 into the equation, we get:
y = (2)^(-2-2)
y = (2)^(-4)
y = 0.0625
For x = 3:
Substituting x = 3 into the equation, we get:
y = (3)^(-3-2)
y = (3)^(-5)
y = 0.0041
Comparing these results with your answers:
X Y
-2 1
-1 -1
0 Undefined (not -2)
1 1
2 0.0625
3 0.0041
We can see that some of your answers are incorrect. The correct answers are as follows:
X Y
-2 1
-1 -1
0 Undefined
1 1
2 0.0625
3 0.0041
