What are the domain and range of the function f(x)= 2x+1
navik [9.2K]

Answer:

Domain: All the real numbers

Range: All the real numbers

Step-by-step explanation:

The domain of a function is the complete set of possible values of the independent variable 'x'. That is to say, all the values that 'x' can take:

In this case, f(x)= 2x+1, the independent variable has no restrictions. Meaning that 'x' can take all the Real Values. In set notation: x∈ℝ.

The range of a function is the complete set of all possible resulting values of the dependent variable 'y'. In this case, given that the independent variable has no restrictions, the dependent variable 'y' can take any value. So, the range is: y ∈ ( −∞, ∞ ) - All the real numbers.

If you go from point (-1, -3) to point (4, 4), you can find the slope of the line using the slope formula.  m= \frac{4-(-3)}{4-(-1)}= \frac{7}{5}.  So our slope is 7/5.  The line goes through the y axis at -3/2, so putting that together we get an equation for the line that is  y= \frac{7}{5}x- \frac{3}{2},  choice D from above.
