F(x) = 2x - 3 and f(x) = f'(x), find the value of x.​
Salsk061 [2.6K]

Answer:

x=1

Step-by-step explanation:

According to your typed question,

f(x)=2x-3

Let f(x)=y

y=2x-3

Now,

Interchanging the positions of x and y

x=2y-3

x+3=2y

x+3/2=y

f'(x)=x+3/2

Then,

f(x)=f'(x)

2x-3=x+3/2

2(2x-3)=x+3

4x-3=x+3

4x-x=3+3

3x=3

x=3/3

x=1

According to your image question,

f(x)=x/2x-3

f(x)=f'(x)

Now,

Let y=f(x)

y=x/2x-3

y(2x-3)=x

2xy-3=x

2xy-x=3

x(2y-1)=3

2y-1=3x

2y=3x+1

y=3x+1/2

f'(x)=3x+1/2

Then,

f(x)=f'(x)

x/2x-3=3x+1/2

2x=6xsq+2x-9x+3

2x=6xsq+7x+3

solve for x ok

M(x)=1/x f(x)=2x-10 find the domain restriction of m(R(x))
AlexFokin [52]

Answer:

  • x ≠ 5

Step-by-step explanation:

<u>Given</u>

  • m(x) = 1/x
  • f(x) = 2x - 10

<u>Composite function</u>

  • m(f(x)) = 1/ (2x - 10)

<u>The denominator can't be zero</u>

  • 2x - 10 ≠ 0
  • 2x ≠ 10
  • x ≠ 5

Suppose y = 2x +10. Find y if x = -2.
liubo4ka [24]

If x = -2, y = 6.


To solve this quesiton, we need to find the value of y if x is equal to -2. We can do this by substiuting the value of x and then solving.


y = 2 (-2) + 10


y = -4 + 10


y = 6
