78 xintercepts of fx x2 x 42 Solutionf x5x2x42 To find the

Solution

f (x)=5/(x²-x-42)

To find the f (x) intercept or y intercept substitute x=0

Then f (x )= 5/(0-0-42)= -5/42 thus that\'s the f (x) or y intercept. x intercept of f (x) doesn\'t exist because on substitution of York f (x)=0 , the function will not exist hence there is no x intercept of f (x).
