The answer for the exercise shown above is the first option, which is:
<span> f(x)=log(x-3)
The explanation is shown below:
If you substitute the x in the function for values, you will obtain the graph attached above. As you can see on the mentioned graph, when the variable x has the value 4, the value y is 0. Therefore, you have:
</span> f(x)=log(x-3)
f(x)=log(4-3)
f(x)=log(1)
f(x)=0<span>
</span>
Y = mx + b
slope(m) = -3
(2,7)...x = 7 and y = 2
now we sub and fund b, the y int
2 = -3(7) + b
2 = -21 + b
2 + 21 = b
23 = b <== ur y int
Step-by-step explanation:
I'm sorry I don't understand the question pls forgive me
They all add up to 2.5 maybe u have to simplify?
Answer:

Step-by-step explanation:
This is for the first question.
Slope-intercept is:

m - slope
b - y-intercept
We are given the slope of
and a y-intercept of 2.
Plug in the values:

Hope this helps.
