Question

f(x) = 3x + 3^x - 2!
f(2) =
f(4) = ​

Answer 1

Jawaban:

f(2) = 13

f(4) = 91

Penjelasan dengan langkah-langkah:

f(x) = 3x + 3^x - 2!

= 3x + 3^x - 2 × 1

= 3x + 3^x - 2

f(2) = 3(2) + 3² - 2

= 6 + 9 - 2

= 15 - 2

= 13

f(4) = 3(4) + 3⁴ - 2

= 12 + 81 - 2

= 93 - 2

= 91

Answer 2

[tex]f(x) = 3x + {3}^{x} - 2![/tex]

*

[tex]f(2) = 3(2) + {3}^{2} - 2·1[/tex]

[tex]f(2) = 3·2 + 9 - 2[/tex]

[tex]f(2) = 6 + 9 - 2[/tex]

[tex]f(2) = 15 - 2[/tex]

[tex]f(2) = 13[/tex]

*

[tex]f(4) = 3(4) + {3}^{4} - 2![/tex]

[tex]f(4) = 3·4 + {3}^{4} - 2·1[/tex]

[tex]f(4) = 12 + 81 - 2[/tex]

[tex]f(4) = 93 - 2[/tex]

[tex]f(4) = 91[/tex]
