f(x) = 6x² + 2
a. f(2) = ...
b. f(3) = ...

f(x) = 6x² + 2

A. f(2)

→ f(2) = 6(2²) + 2

→ f(2) = 6(4) + 2

→ f(2) = 24 + 2

→ f(2) = 26

B. f(3)

→ f(3) = 6(3²) + 2

→ f(3) = 6(9) + 2

→ f(3) = 54 + 2

→ f(3) = 56

f(2) = ...

f(3) = ...

Jawab:

f(x) = 6x² + 2

f(2) = 6(2)² + 2

f(2) = 6(4) + 2

f(2) = 24 + 2

f(2) = 26

f(3) = 6(3)² + 2

f(3) = 6(9) + 2

f(3) = 54 + 2

f(3) = 56
