Please Help! It is Pre-Calc and I need to know the answer!

The limit of a continuous function at a point is just the value of that function at the point.

a. f(x)=10

f(-1)=10

f(x)=x

f(-1)=-1

a. 10 b=-1, choice a

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
