g(x)=12x+3

Rewrite the function as an equation.

y=x2+3

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of m and b using the form y=mx+b.

m=12

b=3

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 12

y-intercept: 3

Slope: 12

y-intercept: 3

Choose 0 to substitute in for x to find the ordered pair.

Replace the variable x with 0 in the expression.

f(0)=02+3

Simplify the result.

Divide 0 by 2.

f(0)=0+3

Add 0 and 3.

f(0)=3

The final answer is 3.

3

3

The y value at x=0 is 3.

y=3

y=3

Choose 2 to substitute in for x to find the ordered pair.

Replace the variable x with 2 in the expression.

f(2)=22+3

Simplify the result.

Divide 2 by 2.

f(2)=1+3

Add 1 and 3.

f(2)=4

The final answer is 4.

4
