Find the sum of both numbers, then divide by 2. That'll give you the median, not the midpoint, which is what I'm assuming you want to find (since you haven't given me any x-y coordinates).
So (0.1+0.2)/2=0.15
Yes it will be 3 since it gradually increases by 3
I believe that the quotient of 7/8 divided by 3/4 is 1.6 repeating and 1.6 repeating is 1 and 2/3 as a fraction so that means that the quotient of 7/8 by 3/4 is greater than 7/8. I hope this helped.
F(x)=-5(x-4)^2+80
f(x)=-5(x²-8x+16)+80
f(x)=-5x²+40x-80+80
f(x)=-5x²+40x
Replace f(x) to y, now switch the location of the variables x and y. Solve for new y.
y=-5x²+40x
x=-5y²+40y
0=-5y²+40y-x
Use quadratic formula to find the value of y.
y=-40+-√(40^2 -4(-5)(-x)/2(-5)
f^-1(x)= (-40+-√1600-20x)/-10 <--- Not too sure about this one :/
Hope I helped :)
