Which statement best describes how to determine whether f(x) = 9 – 4x2 is an odd function? Determine whether 9 – 4(–x)2 is equivalent to 9 – 4x2.
Determine whether 9 – 4(–x2) is equivalent to 9 + 4x2.
Determine whether 9 – 4(–x)2 is equivalent to –(9 – 4x2).
Determine whether 9 – 4(–x2) is equivalent to –(9 + 4x2).

C :Determine whether 9 – 4(–x)² is equivalent to –(9 – 4x²).

Step-by-step explanation:

A function f(x) is odd if f(-x)=-f(x).

We have thus to determine if 9-4*(-x)²= -(9-4*x²).

which is false since this function is even !!!

Answer is C

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
