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:
Answer:
B
Step-by-step explanation:
The graph passes through (0,0) so this point HAS to satisfy the equation.
Let's check this. We put 0 into both x and y and check if the equation holds true:
A) y = -2 NO!
B) y = 0 YES!
C) 1 = 18 NO!
D) y = -2 NO!
Definitely the equation of this graph is B.
Note: If there were more than one "yes" in our checking, then we would have taken another point and boiled it further down. But we didn't need to.
Answer:
B
Step-by-step explanation:
-3 < 2x + 3 <= 5
-6 < 2x <= 2
-3 < x <= 1
such a condition is an "and" condition. both parts need to be fulfilled.
-3 < x and x <= 1
if you are still not seeing it :
-3 < x is the same as x > -3
now you see that B is the right answer.
x > -3 and x <= 1
