<h3>Function and values</h3>
Given the function of the variable x below;
f(x) = 12x+12/x²-1
If the value of x is 7, hence;
f(7) = 12(7)+12/(7)²-1
f(7) = 84+12/48
f(7) = 96/48
f(7) = 2
If the value of x is 4, hence;
f(4) = 12(4)+12/(4)²-1
f(4) = 48+12/15
f(4) = 60/5
f(4) = 12
Hence the value of the function is x is 7 and 4 are 2 and 12 respectively
