Need urgently : (

the graph of the derivative, f '(x) is shown below. on what interval is the graph of f (x) concave up?

graph is a parabola with x intercepts at x equals negative 4 and 2 and y intercept at y equals negative 2

concave up on (−∞, −1)
concave up on (−∞, −∞)
concave up on (−1, ∞)
concave up on (−6, −2)

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
