14. if s and t are normal linear operators satisfying st*-ts and ts*=s*t, show that their sum s+t and product st are normal. 15. show that a bounded linear operator t: hh on a complex hilbert space h is normal if and only if llt*xll-itxll for all xe h. using this, show that for a normal linear operator,

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
