tolong ya makasihhh
Nilai f(-3), f(-2), f(-1), f(0), f(1), f(2), f(3) berturut-turut yaitu:
- f(-3) = [tex]\frac{1}{81}[/tex]
- f(-2) = [tex]\frac{1}{27}[/tex]
- f(-1) = [tex]\frac{1}{9}[/tex]
- f(0) = [tex]\frac{1}{3}[/tex]
- f(1) = 1
- f(2) = 3
- f(3) = 9
Penjelasan dengan langkah-langkah:
Diketahui:
f(x) = 3ˣ⁻¹
Ditanya:
Tentukan nilai dari f(-3), f(-2), f(-1), f(0), f(1), f(2), f(3)
Jawab:
f(-3) = 3⁻³⁻¹= 3⁻⁴ = [tex]\frac{1}{81}[/tex]
f(-2) = 3⁻²⁻¹= 3⁻³ = [tex]\frac{1}{27}[/tex]
f(-1) = 3⁻¹⁻¹= 3⁻² = [tex]\frac{1}{9}[/tex]
f(0) = 3⁰⁻¹ = 3⁻¹ = [tex]\frac{1}{3}[/tex]
f(1) = 3¹⁻¹ = 3⁰ = 1
f(2) = 3²⁻¹ = 3¹ = 3
f(3) = 3³⁻¹ = 3² = 9
