don't be alarmed the two lines just mean absolute value, the problem is asking what is m. the problem is asking what number multipyed by 2, subtracted by 1 will give you 3?
2x2=4 right?
so 4-1=3 there!
m=4
so the problem is 2(4)-1=3
i hope i explained well enough!

Answer:
Step-by-step explanation:
f(x) = x^2 + 3x - x/2
f(x) = x^2 + 2.5x
- 3x - 1/2x =
- 6x/2 - 1/2x =
- 5x/2 =
- 2.5x
f(6) = 6^2 + 2.5*6
f(6) = 36 + 15
f(6) = 51
