= (2*10) + (-3*-4) + 5 (* means multiply)
= 20 + 12 + 5
= 37
1 is 7
and
2 is 1
i hope this is right i haven’t done this math in a while
From -∞ to -4 the blue line is above the X axis which means it is >0
The blue line is negative between -4 and -3
This would make the correct answer: F(x) > 0 over the interval (-∞,-4)
Isk never seen that problem in my life
