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.

1) = 8

2) = 8

Step-by-step 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.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
