Now, If the exponent was negative like you asked....
Answer:
10
Step-by-step explanation:
bh/2
b=5
h=4
=5×4/2
=20/2
=10
A ) The data in this table represents a function.
This function is : f ( x ) = 1/2 x
B ) f 1( 8 ) = 1/2 * 8 = 4 (also from the data in the table)
f 2( 8 ) = 3 * 8 - 10 = 24 - 10 = 14.
Second relation has a greater value when x = 8
C ) f ( x ) = 80
3 x - 10 = 80
3 x = 90
x = 90 : 3
x = 30
