Which set of functions f satisfying the given condition IS NOT a subspace of the vectorial space F(|R) of real functions with real variable. a) f(x) = -f(x), for every x ∈ |R
b) f(0) = 0
c) f(x) = k, for every x ∈ |R, with k as a non zero real constant.
d) f(-x) = f(-x), with x ∈ |R

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
