Step-by-step explanation:

g(x) is a polynomial. It doesn't contain a rational degree with the variable as the denominator, negative eexponents, or irrational coeffecienfs, and no rational exponents as a degree.

f(x) and f(a) isn't a polynomial. It contain a irrational coeffceint like pi. So it not a polynomial. And they both have a rational exponet as a degree

d = 8.6d = √74

Step-by-step explanation:

$A (8, 2) = (x_1 ,y_1)\\ B(3,9) = (x_2,y_2)\\\\d = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\d =\sqrt{\left(3-8\right)^2+\left(9-2\right)^2}\\\\d=\sqrt{(5)^2+(7)^2}\\\\d=\sqrt{25+49}\\\\d=\sqrt{74}\\\\d = 8.6023\\\\d = 8.6$

Find the distance AB between the points A (8, 2) and B(3,9). Round your answer to the nearest

tenth

$f(a) = {a}^{ \frac{1}{2} } + 3a + {a}^{2}$ $f(x) = \frac{9}{17} {x}^{83} + \sqrt{54 {x}^{97} } + \pi$
