Find the area between the two functions
Inga [223]

The area between the two functions is 0

<h3>How to determine the area?</h3>

The functions are given as:

f₁(x)= 1

f₂(x) = |x - 2|

x ∈ [0, 4]

The area between the functions is

A = ∫[f₂(x) - f₁(x) ] dx

The above integral becomes

A = ∫|x - 2| - 1 dx (0 to 4)

When the above is integrated, we have:

A = [(|x - 2|(x - 2))/2 - x] (0 to 4)

Expand the above integral

A = [(|4 - 2|(4 - 2))/2 - 4] - [(|0 - 2|(0 - 2))/2 - 0]

This gives

A = [2 - 4] - [-2- 0]

Evaluate the expression

A = 0

Hence, the area between the two functions is 0

Let f(x)= x2 - 14 and g(x) = 6-X.<br> Find (fq)(7).
sleet_krkn [62]

Answer:

(fg)(7) = - 35

Step-by-step explanation:

The given functions are:

f(x) =  {x}^{2}  - 14

and

g(x) = 6 - x

We want to to find

(fg)(7)

Note that:

(fg)(x) = f(x) \times g(x)

We substitute the functions to obtain:

(fg)(x) = ( {x}^{2} -1 4 ) \times (6 - x)

We now substitute x=7, to get:

(fg)(7) = ( {7}^{2} -1 4 ) \times (6 - 7)

This implies that

(fg)(7) =( 49-1 4 ) \times (6 - 7)

(fg)(7)  = 35 \times  - 1 =  - 35
