Question

Tolong dijawab yaaa mksh

Answer 1

F(x) = 8x + k
f(2) = 15

coba kita masukkan rumus f(x)
f(2) = 8(2) + k = 15
       = 16 + k = 15
                  k = 15-16
                  k = -1

f(-1) + f(0) + f(1) ?
f(-1) = 8(-1) + (-1) = -9
f(0)  = 8(0) + (-1) = -1
f(1)  = 8(1) + (-1) = 7

-9 -1 + 7 = -3
