Question

solve the inequality and graph the solution. 1 ≤ f - 3 plot the endpoints. select an endpoint to change it from closed to open. select the middle of the segment, ray, or line to delete it.

Explanation:

Step1: Isolate the variable f.

Add 3 to both sides of the inequality $1\leq f - 3$. So, $1+3\leq f-3 + 3$.

Step2: Simplify the inequality.

$4\leq f$, which can also be written as $f\geq4$.

Answer:

The solution of the inequality is $f\geq4$. On the number - line, we put a closed circle at 4 (because the inequality is $\geq$) and draw a ray to the right of 4.
