Question

Tolong buatin grafik eksponen dari :
F(x) = 2^x
F(x) = 2^-x
F(x) =3^x
F(x) = 3^-x

Answer 1

Masukkan saja sembarang angka ke masing-masing  fungsi. Angka yang dimasukkan ke fungsi adalah x dan hasil dari fungsi tersebut adalah y, sehingga didapat titik (x, y).
a)
f(x) = 2^x
f(-1) = 2^-1 = 1/2 <=> (-1, 1/2)
f(0) = 2^0 = 1 <=> (0,1)
f(1) = 2^1 = 2 <=> (1, 2)
f(2) = 2^2 = 4 <=> (2, 4)
dst.

b)
f(x) = 2^-x = 1 / 2^x
f(-1) = 2^1= 2 <=> (-1, 2)
f(0) = 1 / 2^0 = 1 <=> (0, 1)
f(1) = 1 / 2^1 = 1/2 <=> (1, 1/2)
f(2) = 1 / 2^2 = 1/4 <=> (2, 1/4)
dst.

c)
f(x) = 3^x
f(-1) = 3^-1 = 1/3 <=> (-1, 1/3)
f(0) = 3^0 = 1 <=> (0, 1)
f(1) = 3^1 = 3 <=> (1, 3)
f(2) = 3^2 = 9 <=> (2, 9)
dst.

d)
f(x) = 3^-x = 1 / 3^x
f(-1) = 3^1= 3 <=> (-1, 3)
f(0) = 1 / 3^0 = 1 <=> (0, 1)
f(1) = 1 / 3^1 = 1/3 <=> (1, 1/3)
f(2) = 1 / 3^2 = 1/9 <=> (2, 1/9)
dst.
