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>
volume for a sphere (ball) is 4/3 x PI x r^3
r = 6.3, r^3 = 6.3^3 = 250.047
volume = 4/3 x 3.14 x 250.047 = 1046.863
rounded to nearest hundredth = 1046.86 cubic inches
The house is 91000 dollars. 14000 x 6.5
