Determine where the graph of the function is concave upward and where it is concave downward. (Enter your answers using interval notation. If the answer cannot be expressed as an interval, enter EMPTY or ∅.) g(x) = 2x3 − 4x

Dexter graphs a quadratic function on a math test. The graph of the function crosses the x-axis at values of -3 and 6. If Dexter graphs the function correctly, which equation could represent the quadratic function? O fx) =x2-3x - 18 O fx) =x2+3x + 18 O fx) =x2-9x - 18 O fx) =x2+9x + 18 https://student.masteryconnect.com/ Type here to search 99+ 近

Find all intercepts of the following function. 4x² – 6x + 6 f(x)= x-4

For the given function, find each of the components. You will upload a picture of your work (not just the answer show how you got the answer); be sure that it is neat and clearly labeled. f(x)=x2−3x−7f(x)=x2-3x-7 a. Find the vertex. b. Find the x-intercepts and write as an ordered pair. c. Find the y-intercept and write as an ordered pair. d. Find the equation of the axis of symmetry. e. Sketch the graph of the function using at least 5 points. 5 points must be identified to receive full credit.
