F(x)=x3 −4x even odd or neither

Dennis_Churaev [7]

The answer is neither.

Let's take an odd number and substitute.

f(3) = 3³ - 4(3)
f(3) = 27 - 12
f(3) = 15 (odd)

Now, let's take an even number.

f(4) = 4³ - 4(4)
f(4) = 64 - 16
f(4) = 48 (even)

Since both even and odd numbers are possible, it is neither.

Last month a museum received €21000 in donations.After taking off the cost of monthly bills,,the museum spent the remaining mone

Rainbow [258]

Answer:

$13,500.

Step-by-step explanation:

Let x represent money spent on monthly bills.

We have been given that last month a museum received €21000 in donations. The ratio of bills to donations was 5:14.

We will use proportions to solve our given problem.

$\frac{\text{Bills}}{\text{Donations}}=\frac{5}{14}$

$\frac{x}{21000}=\frac{5}{14}$

$\frac{x}{21000}*21000=\frac{5}{14}*21000$

$x=5*1500$

$x=7500$

Now, we will subtract $7500 from donations to find the amount spent on new exhibitions as:

$\$21,000-\$7500=\$13,500$

Therefore, they spent $13,500 on new exhibitions.
