Answer:

The value of y is 16.

Step-by-step explanation:

You have to substitute x = 2 into the equation :

[tex]y = {3x}^{2} + 4[/tex]

Let x = 2,

[tex]y = 3( {2)}^{2} + 4[/tex]

[tex]y = 3(4) + 4[/tex]

[tex]y = 12 + 4[/tex]

[tex]y = 16[/tex]

Answer:

y = 16

Step-by-step explanation:

Let's solve your equation together

3x^2 + 4

We have been given that x = 2

So first we must replace x by 2.

y = 3(2)^2 + 4

Now we solve the equation

2^2 = 4

y = 3(4) + 4

3 * 4 = 12

y = 12 + 4

12 + 4 = 16

y = 16

Hope this helps :)
