C. crosses x-axis
this is known as the functions roots or zeros
every function is the product of its roots
That's easy to do, do I want me to give u the answer
Answer:
For all real numbers a except 0, we have
a(1/a) = 1
Step-by-step explanation:
Multiplication of real numbers are having the following properties:
i) commutative = ab = ba
ii) associative a(b+c) =ab+ac
iii) Multiplicative identity element exists such that for any number
a*1 =1*a = a
i.e. 1 is identity.
Inverse property is for any a not equal to 0, we have a real number such that
a*that real number = multiplicative identity
i,.e. a(a real number) = 1, a not equal to 0
In other words, there exists an 1/a for all a not equal to 0 satisfying a*1/a = 1
Answer:
A
Step-by-step explanation:
Answer:
400%
Step-by-step explanation:
you have to times 100% to the number to get a percent of that number.
So we have 4, and we times a 100% to it, which makes it 400%.
Hope it helps!
