ANSWER:


 f(x)=4x-3


Here you are asked to find out the value of  f(-1)



For that replace x by -1 in the given function.




==> f(-1)= 4 (-1) -3



==> f(-1) = -4 - 3



==> f(-1) = -7



To find the vlue of  f(2), f(3), f(-2) etc...just replace x by 2, 3, -2 etc in the given function..



Hope you found the explanation useful
