The value of y in y = 5x if the value of x doubles itself is y also doubles itself; option A

<h3>How to solve equation?</h3>

y = 5x

if x = 2

y = 5(2)

y = 10

if the value of x doubles, for instance, if x = 4

y = 5(4)

y = 20

y = 5/x

if x = 0.5

y = 5/0.5

y = 10

if the value of x triples, for instance, if x = 0.125

y = 5/x

= 5/0.125

y = 40

The value of y in y = 5/x if the value of x triples itself is y also triples itself; option B

If f(y) = e^(9y) + e^(-9y), find f'(y). Use exact values.
Westkost [7]

Given:

f(y)=e^{9y}+e^{-9y}

To find:

The f'(y).

Solution:

Chain rule of differentiation:

[f(g(x))]'=f'(g(x))g'(x)

Differentiation of exponential:

\dfrac{d}{dx}e^x=e^x

We have,

f(y)=e^{9y}+e^{-9y}

Differentiate with respect to y.

f'(y)=e^{9y}\dfrac{d}{dx}(9y)+e^{-9y}\dfrac{d}{dx}(-9y)

f'(y)=e^{9y}\cdot 9(1)+e^{-9y}\cdot (-9)(1)

f'(y)=9e^{9y}-9e^{-9y}

Therefore, the differentiation of the given function is f'(y)=9e^{9y}-9e^{-9y}.

Please please help!!! I really need help on this quarion and I keep getting it wrong :(
Marta_Voda [28]

Answer:

f(x)=x^2+4\\g(x)=4x

(f+g)(x)=x^2+4+4x\\(f+g)(x)=x^2+4x+4

------------------------------------------------------------------

(f-g)(x)=x^2+4-(4x)\\(f-g)(x)=x^2+4-4x\\(f-g)(x)=x^2-4x+4\\

-----------------------------------------------------------------

(f*g)(x)=(x^2+4)(4x)\\(f*g)(x)=4x^3+16x

-----------------------------------------------------------------

(\frac{f}{g})(x)= \frac{x^2+4}{4x} \\
