X=55 Explanation: the square is a right angle symbol and that means the angle is 90 degrees so just subtract 35 from the 90 to get x

F(x) = x2 + 2x-5<br> g(x) = -3/2 - 4x + 1<br> What is f(x) – g(x)?

NeX [460]

Step-by-step explanation:

Start by finding (fog)(x)

To find this function, substitute x=

x−1

That is g(x) into f(x)

⇒(f∘g)(x)=(

x−1

)

−2(

x−1

)+5

(x−1)

−

x−1

Now substitute x=3

⇒(f∘g)(3)=

(3−1)

−

3−1

−

+5=4−4+5=5.

Hope it helps:)

f of x equals 4 x over quantity x squared minus 16. Show all work to identify the asymptotes and zero of the function.

yuradex [85]

Given:

The function is

$f(x)=\dfrac{4x}{x^2-16}$

To find:

The asymptotes and zero of the function.

Solution:

We have,

$f(x)=\dfrac{4x}{x^2-16}$

For zeroes, f(x)=0.

$\dfrac{4x}{x^2-16}=0$

$4x=0$

$x=0$

Therefore, zero of the function is 0.

For vertical asymptote equate the denominator of the function equal to 0.

$x^2-16=0$

$x^2=16$

Taking square root on both sides, we get

$x=\pm \sqrt{16}$

$x=\pm 4$

So, vertical asymptotes are x=-4 and x=4.

Since degree of denominator is greater than degree of numerator, therefore, the horizontal asymptote is y=0.

Chef johnson used 4 1/2 cups of flour to make 4 fruit cakes. How many cups of flour are needed for 1 fruit cake?

Wittaler [7]

Divide 4 1/2 = 4.5 by 4 you would get 4.125. 4.125 cups of flour are needed to make one fruitcake.
