Answer:
f^-1(x) = x - 2
Step-by-step explanation:
To find the inverse of a function in terms of x and y, you would sway x and y in the function. We can rewrite f(x) = x + 2 as y = x + 2, since f(x) is basically y in a function. The inverse of y = x + 2 would be x = y + 2. Now, solve for y.
x = y + 2
-2 both sides.
x - 2 = y
y = x - 2
The inverse of y = x + 2 would be y = x - 2, so the inverse of f(x) = x + 2 would be f^-1(x) = x - 2 (f^-1(x) means the inverse of f(x)).
f^-1(x) = x - 2
I hope you find this helpful. :)
Answer:
option 3
Step-by-step explanation:
x = 2 is a vertical line with an x-intercept of (2, 0) so the answer is Option 3.
Answer:
<h3>3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.</h3>
Step-by-step explanation:
We need to find the unit rate. This found by dividing the price by the number of bananas so we get the price for 1 pound of bananas.
$1.97/5 = $0.39
$1.05/3 = $0.35
<h3>3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.</h3>
