f(x) = sqrt(x)
f(17) = sqrt(17)
it is close to sqrt(16)=4
so to the nearest integer
f(17) = 4
To find the midpoint of a line use the midpoint formula which is M = (x1+x2/2 , y1 +y2/2) After plugging in the coordinates for your variables you should get (-1+5/2, -1+2/2) This simplifies to (2, 1/2) which is the coordinates for the middle point of the base XY.
The square root of 700 is about 26.45, so it lies between 26 and 27
