D, they add up to 90 degrees so they are complementary
Answer:
8666679
Step-by-step explanation:
the answer is 885 and I used a calculator so you should be good :)
The functions has its only zero at x = –4.
The correct answer is option (c) and option (d) both.
To choose the correct function.
What is function?
A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given that:
The value of its function for x=-4 and also think that |-x|=|x|. And then we have:
Put the value of x=-4 in all functions.
(a) f(-4)=|-4–4|=|-8|=8
(b) f(-4)=|-4|+4=4+4=8
(c) f(-4)=|-4+4|=|0|=0
(d) f(-4)=|-4|-4=4–4=0,
However, the functions has its only zero at x = –4 is option (c) and option (d) both.
