Answer:
f(x) = 3.2^n-1
f(x) = 2x4 ^n-1
f(x) = 2x6^n-1
Step-by-step explanation:
1)
<h3>f(x) = 3.2^n-1</h3>
f(1) = 3x2^(1-1)
= 3x1
= 3
f(2)= 3x2^n-1
= 3x2 ^(2-1)
= 3x2
= 6
f(3)= 3x2^(3-1)
= 3x2^2
= 3x4
= 12
<h3>
2)</h3><h3>
f(x) = 2x4 ^n-1</h3>
f(1) = 2x4^(1-1)
= 2x1
= 2
f(2) = 2x4^(2-1)
= 2x4
= 8
f(3) = 2x4^(3-1)
= 2x4^2
= 2.16
= 32
<h3>3)</h3><h3>f(x) = 2x6^n-1</h3>
= 2x6 ^(1-1)
= 2x1
= 2
f(2) = 2x6^(2-1)
= 2x6
= 12
f(3) = 2x6^(3-1)
= 2x6^2
= 2x36
= 72
