Jenna created the graph below to represent the solution to the inequality Negative 6 less-than x. A number line going from negative 9 to positive 1. A closed circle is at negative 6. Everything to the right of the circle is shaded.

What error did she make?
She should have used an open circle at the end of the ray.
She should have pointed the arrow to the left.
She should have ended the ray with a circle at –5.
She should have ended the ray with a circle at –7.

Step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

that is the sum
