Decide whether the function is polynomial function. If so, write it in standard form and state its degree, type, and leading coefficient. f(x)= 9x^4 + 8x^3 - 6x^-2 + 2x

mean, 40.6

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
