Question

identify the function that is odd
a) g(x)= -2x^4+2x^2-4
b) p(x)= -2x^3/ -2x^2+2
c) h(x)= l -2x+2 l -2
d) f(x)= -4x^3-4x^2-4

Answer 1

a function F(x) is even if F(x) =F(-x)
a function F(x) is odd if F(x) =-F(-x)
so, the first step will be to replace x = -x in each of the functions, and check which ones satisfy the odd function condition

Answer 2

b?

Answer 3

yup! you are correct :)

Answer 4

i have another question

Answer 5

ask :)

Answer 6

translate the problem into symbols... the cost in dollars of filling up your gas tank is directly proportional to the price per gallon of gas. D= dollar to fill tank p= price per gallon

Answer 7

dollar D directly proportional to price/gallon P
