Well since we can use a base of 1 we know that 1 - 45 is less than 4 but -1 + 45 is not, which follows the assumption that x>0, but now we need to know what x is less than to fit the inequality. If we use 5 as a trial we can see that 5 - 9 = -4 so 0<x<5 is your answer. Hope this helps I basically used trial and error. If you want to check try 3 or 4 for x and it will work but 6 will not.
X= 7
This is because of you plug in 7 for x into the equation it will give you 28-10 which is 18.
Answer:
9-3x=0
Step-by-step explanation:
Add 3x to both sides
9=3x
divide both sides by 3
3=x
x=3
It's f(x) = sin2x
Because when you multiply x by any number greater than 1, the graph will shrink.
Try but pi/2 in the equation you will get sin(pi) which is 0. And that satisfies the gragh.
Answer: y= 2 • (1/3)^x-2 -2
hope this helps!
