Question

Find the missing value to make the point (2, __) on the equation y=9x
2
+ 2.

Answer 1

To find the missing value in the point \((2, \_\_)\) on the equation \(y = 9x^2 + 2\), we need to substitute \(x = 2\) into the equation.

Let's do that step by step:

1. Substitute \(x = 2\) into the equation:
\[
y = 9(2^2) + 2
\]

2. Calculate \(2^2\):
\[
2^2 = 4
\]

3. Multiply by 9:
\[
9 \times 4 = 36
\]

4. Add 2:
\[
36 + 2 = 38
\]

So, when \(x = 2\), \(y = 38\).

Therefore, the missing value is \(38\), making the point \((2, 38)\).
