Well you will need two number that are divisible by 30 and add up to -7 so they will have to be a negative.
I would try -2 and -5 which are both divisible by 30 and ad up to -7 so...
-2/30 + -5/30 = -7/30
16 would be the range. The lowest value is 5, and the highest value is 21. You just subtract those two which gives you 16! (:
Answer:
The correct option is D)
.
Step-by-step explanation:
Consider the provided cubic function.
We need to find the equation having zeros: Square root of two, negative Square root of two, and -2.
A "zero" of a given function is an input value that produces an output of 0.
Substitute the value of zeros in the provided options to check.
Substitute x=-2 in
.

Therefore, the option is incorrect.
Substitute x=-2 in
.

Therefore, the option is incorrect.
Substitute x=-2 in
.

Therefore, the option is incorrect.
Substitute x=-2 in
.

Now check for other roots as well.
Substitute x=√2 in
.

Substitute x=-√2 in
.

Therefore, the option is correct.
