Step-by-step explanation:
g(x) = 3^ x .
h(x) = 2^-x
We want to subtract them
f(x) = 3^x - 2^(-x)
I will rewrite without the negative exponent
f(x) = 3^x - (1/2)^(x)
Lets pick a couple of points
f(0) = 3^0 - (1/2) ^ 0 = 1-1 = 0
As x gets large 3^x gets large and 1/2^x gets close to 0, so it will get large
As x goes to negative infinity, 3^x goes to zero and 1/2^ gets large so we get - infinitity
Let's say the original price was "x", thus "x" is the 100%, and we know that 15 is 80% of that, thus
Answer:
y= what? Whats the first equation
Step-by-step explanation:
6 bags of dog food × $9 = 54
$89 total - $54 spent on dog food = $35 spent on cat food
$35 / $8 = 4.375, but you can't have decimals for cat food bags so round down.
= 4 bags of cat food
