No its not a function :)
<span>to find the inverse function first expand those brackets </span>
<span>you'll get </span>
<span>f(x)= x^2 - 2x^2 - 2x^2 = 4x^2 </span>
<span>f(x)= x^2 - 4x^2 + 4x^2 </span>
<span>f(x)= x^2 or y=x^2 </span>
<span>to find the inverse, swap x and y around. then make y the subject again </span>
<span>y=x^2 </span>
<span>x=y^2 </span>
<span>Root of x=y </span>
<span>now put -1 into x </span>
<span>it wont work because roots cannot have negative numbers </span>
<span>answer is no</span>
2x-3=-4x+-9
2x-3=-4x-9
negative number and positive number= negative number
2x-3=-4x-9
2x+4x-3=-4x+4x-9
6x-3=-9
6x-3+3=-9+3
6x=-6
Divide by 6
6x/6=-6/6
x=-1
Check answer by using substitution method
2(-1)-3=-4(-1)+-9
-5=-4-9
-5=-5
Answer is x=-1
10/0.1=100
so 10 is 100 times greater than 0.1
Hope this Helps :)
Answer:
Step-by-step explanation:
cos(x) = 179/202
x = arccos(0.886138613861)
x = 27.608033...
x = 28°
