F = 4
if f(x)=11, you must always try and get x alone, so f = (11+5)/4, and this simplifies to 4.
Answer:
d
Step-by-step explanation:
becuse the first one would be 4x and the other ones 2x
No solution but the equation is true
Answer:
Step-by-step explanation:
We look for where 
. The way you find the answer is first, find the point 
. Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).
Using this method here, we see that 
intersects our line at 
, so .
Answer:
