In order to find the value of g(4)+f(-3), we must substitute those values into the functions first.
Substitute -3 into f(x).
f(x)=x²
f(-3)=(-3)²
f(-3)=9
Substitute 4 into g(x).
g(x)=2x-3
g(4)=2(4)-3
Using the rules of PEMDAS, multiply first then subtract.
g(4)=8-3
g(4)=5
Therefore, if f(-3) is 9 and g(4) is 5, we must add the two values together.
5+9=14
<u>The value of g(4)+f(-3) is 14.</u>

Answer:
DJ = 48
Step-by-step explanation:
The centroid (J) divides the median into parts that have the ratio 2:1.
DJ : JH = 2 : 1
DJ : (DJ +JH) = 2 : (2+1)
DJ : DH = 2 : 3
DJ = (2/3)DH = (2/3)(72)
DJ = 48
