Answer:
B
Step-by-step explanation:
James can eliminate $25 from Food/Clothes and $27 from Entertainment
All you have to do is plug in the given x values. your first equations would read:
f(-3) = 2^(-3)
f(-2) = 2^(-2)
f(-1) = 2^(-1)
these can be solved by moving decimal points or entering them into a calculator. regardless of the method, your answers are:
f(-3) = 0.002
f(-2) = 0.02
f(-1) = 0.2
so just repeat that process to fill in the rest of your table. to graph it, you'll use them as normal (x, y) points:
(-3, 0.002)
(-2, 0.02)
(-1, 0.2)
the graph might be a little difficult, working with such small values, but precision isn't totally important--0.002 will be super close to 0, 0.02 will be slightly further, 0.2 will be slightly further. the smaller values don't matter as much graphically and you'll recognize the graph of a growing exponential as you graph more of the table.
.6 because it is very low compared to the other numbers
Answer:
22/7 is not pi
Step-by-step explanation:
22/7 is just a close approximation for pi, not pi itself.
If you put 22/7 into a calculator, you get:
3.142857...
While the number pi itself is:
3.1415926...
You can notice that pi is actually different than 22/7, even though the two numbers start out the same and are close to each other. Frequently in geometry, you use 22/7 as pi because it's so close and makes calculation easier.
Hope this helps!
Answer:
(-2,-12) and (1,30)
Step-by-step explanation:
we know that
f(x) passes through the points (-2,-4) and (1,10)
That means
For x=-2 ----> f(-2)=-4
For x=1 ----> f(1)=10
we have
g(x)=3f(x)
so
substitute the given value of f(x) to obtain the value of the function g(x)
For x=-2 -----> g(-2)=3f(-2) ----> g(-2)=3(-4)=-12
For x=1 -----> g(1)=3f(1) ----> g(1)=3(10)=30
therefore
The two points that would lie on the graph of function g are
(-2,-12) and (1,30)
