How do I find the list of points on a graph of f, where x=2? If previously x=2, f(x) =8? I'm unsure how to find the answer and write it correctly.

Can you check my answers.

5- -5 5 -5- Determine the values of a, b, c, and d so the function (a - a) (x + 1) (x + b) (x- c) (x + d) (x + 3) f (x) = correctly model the graph. (a, b, c, and d are all whole numbers) a = 5,

When nutrients for a bacteria culture are exhausted, the bacteria culture goes through the death, or decay, phase of the bacteria growth curve. The following graph shows the number of living bacteria in the colony as a function of time, in hours, after the start of the decay phase. Determine the statement that correctly interprets the graph of the function.
