Answer:
43 is the answer to your question
Answer:
The graph of given function is shown below.
Step-by-step explanation:
The parent natural logarithmic function is

The given function is

It means
.... (1)
The translation is defined as
.... (2)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
On comparing (1) and (2) we get

It means the graph of parent function shifts 5 units up to get the graph of given function.
Table of values:
x y
0.25 3.614
0.5 4.307
1 5
2 5.693
Plot these points on a coordinate plane connect then by a free hand curve.
The graph of given function is shown below.
we have
1 donut -----> 570 calories
7 donuts ----> 600 calories
7 donuts ----> 510 calories
4 donuts ----> 480 calories
3 donuts ----> 400 calories
so
total donuts=1+7+7+4+3=22 donuts
the means is equal to
mean=(1*700+7*600+7*510+4*480+3*300)/22
mean=11,460/22
<h2>mean=521 calories</h2>
Part 2
Find out the median
order the data set from less to greater
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
the median is the middle of the data set
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
<h2>the median is 510 calories</h2>
(2/3a • 9a) + (2/3 • 6) = 23.8
a = 2.1259 or 287/135
