The domain is found within the set of parenthesis. The starting point of that graph has moved from the origin to (4, 4), therefore, the domain is x is greater than or equal to 4.

Hi I´ll help you with this

Remember that the logarithms (log) are just defined when (x) is >0

for example logx is just defined when x>0

So, to obtain the domain of the function log(x-4)+4 , we need to know where the function is defined, and we obtain the result by doing the next steps

x-4>0

x>4

So the answer is that the given function is defined when x>4 or it can be written as (4,∞)

I hope this explanaition helped you

Answer:

f(-1)=3

Step-by-step explanation:

f(x)=x^2-6x+3x-1

f(x)=x^2-3x-1

f(-1)=(-1)^2-3(-1)-1

f(-1)=1+3-1

f(-1)=4-1

f(-1)=3

The simplified form of the equation is $\rm -69.19x+38.2$ .

<h2>Given that</h2>

Equation; $\rm -9.2(8x - 4) + 0.7(2 + 6.3x)$

<h3>We have to determine</h3>

The simplified form of the equation;

<h3>According to the question</h3>

To determine the simplified form of the equation following all the steps given below.

Equation; $\rm -9.2(8x - 4) + 0.7(2 + 6.3x)$

<h3>To simplify the equation multiple the terms and solve.</h3>

Then,

The simplified form of the equation is,

$\rm =-9.2(8x - 4) + 0.7(2 + 6.3x)\\
\\
= (-9.2) (8x)- (-9.2)(4) + (0.7)(2) + (0.7) (6.3x)\\
\\
=-73.6x -(-36.8) +(1.4)+(4.41x)\\
\\
= -73.6x+36.8+1.4+4.41x\\
\\
=-69.19x+38.2$
