So if an equation was f(x)=x+4
you would automatically change f(x) into y
so it would y-y=x(x-x)
so you plug in the x and 4 which is the first y and x
y-4=x(x-x)
you switch the numbers around
so your final answer would be x-4
Answer:

Step-by-step explanation:
i did it before
Answer:
If you mean 2 and 3 it would be (x-2)(x-3)=0
Step-by-step explanation:
(x-2)=0
x-2=0 move the two on the other side to get positive
x=2
(x-3)=0
x-3=0 move the three on the other side to get positive
x=3
Answer:
The third one
Step-by-step explanation:
Its asking if its positive in the interval [-3, -2]
Which means you only look at the graph from -3, -2 on the x axis and we are looking see which one is positive in that space. And by positive it means going up in a positive direction. Only the third one does this.
1 time=2mins
xtimes=30mins
30/2 ×1= 15.
Therefore it can be completed 15 times in 30mins
