45
Step-by-step explanation:
So you have the equation:
(3x - 5) ^(x) - 19
and the value x = 3,

(3*3 - 5) ^ (3) - 19
(9 - 5)^(3) - 19
(4)^(3) - 19
64 - 19

Assuming that

is the amount of hours spent doing homework:
Plug in

for


,

That means that since a

value is the test score (because that's what the y-axis is labeled), your predicted test score is a
64.
Answer:
it might go like A= 12 B= 0 C = -6
