Answer:
6. f(1)+g(2) = 4
8. g(4)-f(0) = 18
10. 2g(-4) = 22
Explanation:
Put the number where the variable is and do the arithmetic.
6.
f(1) = 2·1 -5 = -3
g(2) = |-3·2-1| = |-7| = 7
f(1) + g(2) = -3 + 7 = 4
___
8.
g(4) = |-3·4 -1| = |-13| = 13
f(0) = 2·0 -5 = -5
g(4) - f(0) = 13 -(-5) = 18
___
10.
g(-4) = |-3·(-4)-1| = |11| = 11
2g(-4) = 2·11 = 22
