The answer is x=2 i hope this helps !!
Answer:
11 miles
Step-by-step explanation:
After the first hour, they walk 3 more hours at 2 miles per hour. So, the total distance is ...
5 mi + (3 h)(2 mi/h) = 5 mi + 6 mi = 11 mi
The blue team will walk 11 miles in 4 hours.
To find the inverse of this function, we first need to replace f(x) with y.
y = 2x^2 + 3
Now, we swap x and y
x = 2y^2 + 3
Now, we solve for y.
-3
x - 3 = 2y^2
Sqrt both sides.
√(x - 3) = 2y
Divide by 2
√(x - 3)/2 = y
Replace y with f^-1(x)
√(x - 3)/2 = f^-1(x)
Just realized you were asking for f(-1), not f^-1(x)
Feels bad.
f(-1) = 2(-1^2 + 3)
f(-1) = 2(-1^5)
f(-1) = 2(-1)
<u>f(-1) = -2</u>
I'm leaving the original answer in case you also need the inverse function. :)
