Based on the graph of the function which of the following statements are true?

on the interval

on the interval

on the interval

on the interval

Step-by-step explanation:

Remember that . When the graph of the function is below the x-axis, the value of is negative; therefore the function is less than zero, or in math notation: . On the other hand, when the graph of the function is above the x-axis, the value of is positive; therefore, the function is grater than zero, or in math notation: .

We can infer from our graph that our function is bellow the x-axis from minus infinity to minus -1, and form three to infinity. In math notation:

on the interval and on the interval

We can also infer from our graph that our function is above the x-axis from 1 to 3, so:

on the interval

Knowing this we can conclude that the true statements are:

on the interval

on the interval

on the interval

on the interval

-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
