On Desmos, the derivative (slope) of a function can be shown by using a "prime" (apostrophe) after the function name. Here, we've drawn a dashed blue curve to show where the slope of g(x) exceeds that of f(x). g(x) has a greater slope for all values of x that are more than 4. Any interval bounded by 4 on the left end will be an interval in which the slope of g(x) exceeds the slope of f(x).
Without the graphing calculator, you can estimate that that a line parallel to f(x) will be tangent to g(x) at about x=4. Then for points to the right of that, g(x) has greater slope. Your interval [4, 5] is the only offering for Blank 1 that is appropriate.
The slope of any linear function will "remain constant", so you only need to decide if the slope of g(x) is increasing or decreasing. Your consideration of the curve already should tell you the slope will "increase" as x gets larger.
The value of f(x) is very close to the value of g(x) at x=7. They are the same when x is about x = 7.016. Up to that point, f(x) is larger. f(7) = 27; g(7) = 26.8435456. There should be no argument.
An exponential function eventually exceeds any kind of polynomial function as x gets large.
Not completely sure what graph you are looking for but here is what I got, (-2,-15/4) hope this helps!
Answer:
you are subtracting 2 so it would be like
-7,-9,-11,-13,-15,-17,-19
Answer:
18
Step-by-step explanation:
81π=πr^2
r= 9,-9
9+9=18
Your marked down price would be $562.02. I included a picture of how I got that, but I'll try to explain it as well. 0.87 in a percentage is 87% (I know this because in order to get a percentage you multiply 0.87 by 100 and get 87%). Once I did that I set up a ratio where I made 100% and $646.00 equal to each other because that is the original price. And I made 87% equal to nothing or if you want to you can put x there. I then cross multiplied 87 and 646 which gave me 56202, and then divided that number by 100 which gave me my answer of $562.02, which is 87% of your original price.
