What is the graph of y = cos(x) +3?
2 answers:
Answer:
Given function: f(x) = cos x + 3
To Draw: Graph of f(x)
As we know graph of trigonometric function cos x is a continuous graph with amplitude 1 .i.e., graph is 1 unit above and 1 unit down from the middle of graph.
If we add a constant to the trigonometric function it does not change any thing it just shift the function up or down according to value of constant.
Here 3 is added to cos x ⇒ Gr pah of cos x will be shifted 3 units upward.
Therefore, The graph we obtain is attached.

Answer:
a. Ameribank-$15,157.50
b. Capital Two-$4,646.25
Step-by-step explanation:
a. Tad's savings is $15,000, we calculate his total amount at the end of the year for each bank:
#Ameribank
#Huffington( we use the effective rate to calculate the compound amount):
#Sixth-Third, Take 1 yrs=52 weeks:
#Hence, Ameribank is the best option as his money grows to $15,157.50 which is greater than all the remaining two options.
b. We use the compound interest formula to determine which bank gives the best option:
#Capital Two. r=3.75%, n=12,t=4
#J.C Morgan, t=2, r=3.55% n=12
#Silverman Slacks, n=12,t=3, r=3.65%
We compare the investment amounts after t years:
Hence, Capital two is the best option with an investment amount of $4,646.25

<em><u>Answer</u></em>:
q=-10
<em><u>Step-by-step explanation:</u></em>
D:y=-3x+q
let’s find q
A(-4,2)∈D ⇔ 2=-3(-4)+q ⇔ q=-10
then D:y=-3x-10
