Question

1) f(x) 8 If m 4, find lim f(x) x 5 x X 5.

2) If lim f(x) 8 f(x). 7, find lim X 5 X-5 X 5
3) lim f(x) X 5, find lim.

Answer 1

1) = 8

2) = 8

Explanation:

The concept applied is that of limting value of a fucntion. equate the lim to the value on the RHS, cross multiply and find an expression for f(x). thereafter, subtitute the new value of x in the expression for f(x). Thee detailed steps is as shown in the attachment.
