To find the inverse we have to first change the function notation to 'y'
So
f(x) = -x becomes y = -x
Next, we have to switch the x and y values
So, y = -x becomes x = -y
Now, we have to solve for y.
y = -x
So the inverse of f(x) = -x is:
So
f(x) = -x becomes y = -x
Next, we have to switch the x and y values
So, y = -x becomes x = -y
Now, we have to solve for y.
y = -x
So the inverse of f(x) = -x is:
First, we add 25w on both sides to give us a positive expression for w:
Next, minus 200 from both sides to isolate the expression for w:
Now we divide by 25 on both sides to obtain the inequality for w:
So
Next, minus 200 from both sides to isolate the expression for w:
Now we divide by 25 on both sides to obtain the inequality for w:
So
