What is the domain and range for f (x)= -x2+4×-3

Question

Please help

Answer 1

f=-x^2+4x-3

domain...-infinity tu + infinity

for big x, -x^2 dominate so f gotu - infinity

for negativ x, -x^2 gotu - infinity

Yu get reesunabel numbers neer x=0,f=-3

at x=1, f=0, at x=2, f=1, at x=3, f=0, for bigger x, f negativ

at x=-1, f=-8, & for smaller x, f get smaller

Answer 2

The function is defined for all real x, so the domain is {+infinity, -infinity} . Also, f(x) can take on any value,so the range is also {f belongs to R:f<=1}
