the given expression is,
f(x) = -3x + 5 ......(1)
g(x) = 6x ......(2)
now, put x = -2 in equation (1)
f(-2) = -3(-2) + 5
= 6 + 5
= 11
so, f(-2) = 11
now put, x = 0 in the equation (1)
f(0) = -3(0) + 5
= 0 + 5
= 5
so, f(0) = 5
now, put , x = -3 in equation (2)
g(-3) = 6 (-3) = -18
so, g(-3) = -18
put x = 2 in equation (2)
g(2) = 6(2)
= 12
so, g(2) = 12
