Karo-lina-s [1.5K]

Answer:

f_{1} :Z \rightarrow Z is one to one mapping, it is not onto mapping

Step-by-step explanation:

f_{1} :Z \rightarrow Z\\ f_{1} (x) = x^{3}

f₁(x) is one to one mapping

Let x, y \epsilon Z

f₁(x) = f₁(y):

x₁³ = y₁³

f₁(x) is not onto mapping

Example: If f₁(x) = 7,

x₁³ = 7

x_{1} = \sqrt[3]{7}

x₁ is not an element of Z

f_{1} :Z \rightarrow Z is one to one mapping, it is not onto mapping

Answer:

(A) Your friend will save $282.

(B) Your friend will get 23.5% off the original price of the mattress.

Step-by-step explanation:

We first need to find out the price of the mattress after the 15% discount. Our first step is to find what 15% of 1,200 is. We can do this by multiplying the two numbers.

1,200 x 15% -----> 1,200 x 0.15= 180.

15% of $1,200 is $180.

Next subtract $180 from $1,200, which equals $1,020. We can now apply the 10% off internet coupon.

1,020 x 10% ------> 1,020 x 0.10= 102.

10% of $1,020 is $102.

Next we subtract $102 from $1,020 and we get $918, the final price of the discounted mattress.

We subtract to see how much money the friend saved.

$1,200 - $918= $282.

We can get the percentage by dividing $282 by $1,200.

282 / 1200= 0.235 decimal form ----> 23.5%
