A function is shown below. h(x) =
(1/x - 15 for
x S-4
20 - 3x2
for x>-4
What is the value of h(-4) + 3h(-2)?

step-by-step explanation:

y=mx+b

f is the midpoint of

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer is y = 11.54

hope this : )
