Answer:

The function is even because f(x) = f(−x).

Step-by-step explanation:

we know that

An even function is one for which  

f (−x)=f(x) for all x in its domain.

An odd function is one for which  

f( −x) =−f(x) for all x in its domain

In this problem we have

f(x)=3x^{4}

so

f(-x)=3(-x)^{4}=3x^{4}

therefore

f (x)=f(-x) for all x in its domain.

Answer:

Option A) The function is even because f(x) = f(−x).

Step-by-step explanation:

We are given the following in the question:

f(x) = 3x^4

We have to check whether the given function is odd or even.

Even function:

  • f(-x) = f(x)

Odd function:

  • f(-x) = -f(x)

To check, we evaluate f(-x)

f(x) = 3x^4\\f(-x) = 3(-x)^4 = 3(-1)^4(x)^4 = 3x^4 = f(x)

Thus, the given function is even.

Answer:

-4i =  4(cos 270 +i sin 270)

Step-by-step explanation:

We have a+ib = r(cosθ+isinθ)

r=\sqrt{a^2+b^2}\texttt{ and }tan\theta =\frac{b}{a}

Here a = 0  and b = -4

Substituting

       r=\sqrt{0^2+(-4)^2}\\\\r=4\\\\tan\theta =\frac{-4}{0}\\\\\theta =270^0\texttt{(Since a is zero and b is negative)}

-4i =  4(cos 270 +i sin 270)

Find the distance between the two points rounding to the nearest tenth
mixas84 [53]

Answer:

8.54

Step-by-step explanation:

formula:

d=\sqrt{(x2-x1)^2 + (y2-y1)^2}

d=\sqrt{(-4 - (-7))^2 + (0-(-8))^2}

d=\sqrt{3^2 + 8^2}

d=\sqrt{9 + 64}

d=\sqrt{73}

d= 8.54
