Step-by-step explanation:
The current function of time is defined as follows:

where
is the charge function.
For the given charge function of time
we have the following current function:

In the problem it is proposed that
.
Examining the expression of
we obtained by deriving
with the expression proposed by the problem and comparing term by term:

We conclude that
and
.
Answer:
1) The graph is as shown at the attached figure.
2) The line passes with (1,-3) and (2,-2)
Step-by-step explanation:
graph the line that passes with (3,-1) and has a y-intercept of -4
y-intercept is the value of y when x = 0
So, the line passes with (0 , -4)
The general form of the line y = mx + c
Where m is the slope and c is y-intercept
given y-intercept = -4 ⇒ ∴ c = -4
using the other point to find m
So, when x = 3 , y = -1
So, -1 = 3m - 4
Solve for m
3m = -1 + 4 = 3
m= 3/3 = 1
So, the equation of the line ⇒ <u>y = x - 4</u>
See the attached figure which represents the graph of the line
As shown at the graph the line passes through the points <u>(1,-3) and (2,-2)</u>
Answer: 7 people
Step-by-step explanation: The answer is 7. 1 mother, 1 father, 4 daughters, but the daughters are sisters and they all have the same brother. If they ha 4 sons it would be 4 brothers each. 4+1+1+1=7.
