Will someone me with the 3 highlighted questions?

6. f(1)+g(2) = 4

8. g(4)-f(0) = 18

10. 2g(-4) = 22

Put the number where the variable is and do the arithmetic.

f(1) = 2·1 -5 = -3

g(2) = |-3·2-1| = |-7| = 7

f(1) + g(2) = -3 + 7 = 4

___

g(4) = |-3·4 -1| = |-13| = 13

f(0) = 2·0 -5 = -5

g(4) - f(0) = 13 -(-5) = 18

___

g(-4) = |-3·(-4)-1| = |11| = 11

2g(-4) = 2·11 = 22

hope this is what you were asking for!
