Graph Using a Table of Values y=x^2+3

$y = x^{2} + 3$

Step 1

Substitute $- 2$ for $x$ and find the result for $y$ .

$y = {(- 2)}^{2} + 3$

Step 2

Simplify ${(- 2)}^{2} + 3$ .

Raise $- 2$ to the power of $2$ .

$y = 4 + 3$

Add $4$ and $3$ .

$y = 7$

Step 3

Substitute $- 1$ for $x$ and find the result for $y$ .

$y = {(- 1)}^{2} + 3$

Step 4

Simplify ${(- 1)}^{2} + 3$ .

Raise $- 1$ to the power of $2$ .

$y = 1 + 3$

Add $1$ and $3$ .

$y = 4$

Step 5

Substitute $0$ for $x$ and find the result for $y$ .

$y = {(0)}^{2} + 3$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = 0^{2} + 3$

Remove parentheses.

$y = {(0)}^{2} + 3$

Simplify ${(0)}^{2} + 3$ .

Raising $0$ to any positive power yields $0$ .

$y = 0 + 3$

Add $0$ and $3$ .

$y = 3$

Step 7

Substitute $1$ for $x$ and find the result for $y$ .

$y = {(1)}^{2} + 3$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = 1^{2} + 3$

Remove parentheses.

$y = {(1)}^{2} + 3$

Simplify ${(1)}^{2} + 3$ .

One to any power is one.

$y = 1 + 3$

Add $1$ and $3$ .

$y = 4$

Step 9

Substitute $2$ for $x$ and find the result for $y$ .

$y = {(2)}^{2} + 3$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = 2^{2} + 3$

Remove parentheses.

$y = {(2)}^{2} + 3$

Simplify ${(2)}^{2} + 3$ .

Raise $2$ to the power of $2$ .

$y = 4 + 3$

Add $4$ and $3$ .

$y = 7$

Step 11

This is a table of possible values to use when graphing the equation.

$\begin{array}{c} x & y \\ - 2 & 7 \\ - 1 & 4 \\ 0 & 3 \\ 1 & 4 \\ 2 & 7 \end{array}$
