Diketahui fungsi F(x) =4+ax. Jika diketahui f(-1)=1 tentukan A.F(1/2) B.F(-2) C.F(3/4) MOHON DIJAWAB BESOK DIKUMPUL

pertama cari dahulu nilai a
F(x) = 4 + ax
F(-1) = 4 + (-1)a = 1
(-1)a = 1 - 4
(-1)a = -3
a = -3 / -1
a = 3

A. F(1/2)
F(1/2) = 4 + 3(1/2)
F(1/2) = 4 + 3/2
F(1/2) = 8/2 + 3/2
F(1/2) = 11/2 atau 5,5 atau 5 1/2

B. F(-2)
F(-2) = 4 + 3(-2)
F(-2) = 4 + (-6)
F(-2) = -2

C. F(3/4)
F(3/4) = 4 + 3(3/4)
F(3/4) = 4 + 9/4
F(3/4) = 16/4 + 9/4
F(3/4) = 25/4 atau 6,25 atau 6 1/4
