Examples

y = 4 x^{2} - 2

$y = 4 x^{2} - 2$ ,

x = 2

$x = 2$

Step 1

Substitute

2

$2$ in for

x

$x$ .

y = 4 {(2)}^{2} - 2

$y = 4 {(2)}^{2} - 2$

Step 2

Solve for

y

$y$ .

Step 2.1

Remove parentheses.

y = 4 \cdot 2^{2} - 2

$y = 4 \cdot 2^{2} - 2$

Step 2.2

Remove parentheses.

y = 4 {(2)}^{2} - 2

$y = 4 {(2)}^{2} - 2$

Step 2.3

Simplify

Step 2.3.1.1

Raise

2

$2$ to the power of

2

$2$ .

y = 4 \cdot 4 - 2

$y = 4 \cdot 4 - 2$

Step 2.3.1.2

Multiply

4

$4$ by

4

$4$ .

y = 16 - 2

$y = 16 - 2$

y = 16 - 2

$y = 16 - 2$

Step 2.3.2

Subtract

2

$2$ from

16

$16$ .

y = 14

$y = 14$

y = 14

$y = 14$

y = 14

$y = 14$
