Answer:

See Below.

Explanation:

`\large\begin{gathered} \sf{Start \ by \ plugging \ in \ the \ number \ that \ x \ is: 1} \\ \sf{Now, \ evaluate: y=3*1*2^1+4} \\ \sf{y=3*2+4} \\ \sf{Multiply \ 3 * 2 \ first: y=6+4} \\ \sf{Now, \ just \ add: y=10}{ \end{gathered}`

Done!!

Answer 2

See below.

Explanation:

Is the equation written correctly?

y = 3×2¹ +4 has no variable, unless the "3×2" is supposed to be "3x*2^1"

If so,

y = 3x*2¹ +4 for x = 1 would be

y = 3(1)2¹ +4

y = 3*2 +4

y = 10
