Question

Tolong dijawab dengan cara buat bsk plisssss

Answer 1

F(x) = 8x +k
f(2) = 15
15 = 8x + k
15 = 8×2 + k
15 = 16+k
k= 15-16= -1
___________

A) f(-1) = 8x +k
= 8×(-1) +k
= -8 +(-1)
= -9

B. f(0)= 8x + k
= 8×0+(-1)
= -1
C. f(1) = 8x + k
= 8×1+(-1)
= 7
f(-1) + f(0) + f(1)
= -9 + (-1) +7
= -3 jawaban c
