Question

find the range of the function x//2 -6x+11 for all x€R​

Answer 1

Answer:

Step-by-step explanation    let us simplify it first

x/2-6x+11 =(x-12x+11)/2=(11-13x)/2

y=(11-13x)/2      

11-2y=13x

x=(11-2y)/13

set of all values of y is range of function here and  domain(set of all value of x ) is real for all value of y  therefore y can take any value

hence range of function is all real numbers  

if you have doubt that some real number can not be in the range of function   you can check this by putting value of that real number in y is x is real than chosen real number exists in range of the function

Answer 2

Your answer is 56.

OK dear...
