Answer:
The average rate of change of f(x) from 2-3 is 0.176
Step-by-step explanation:
Rate of change= change in y / change in x
= log 3 - log 2 / 3-2
= 0.477-0.301 / 1
= 0.176
Answer: (8,0) and (0,-4)
Step-by-step explanation:
The x-intercept of an equation is when the equation touches the x-axis which is also where y = 0
So the x coordinate of the x-intercept is -2x + 0 = -16 as y = 0
x = 8 so the x-intercept is (8,0)
The y-intercept of an equation is when the equation touches the y-axis which is also where x = 0
So the y coordinate of the y-intercept is 0 + 4y = -16 as x = 0
y = -4 so the y intercept is (0,-4)
Firstly, the word rational...is derived from ratio..which in simple terms ..is a fraction. a rational function, like all functions, must contain both an independent and dependent variable. The general form of a function is y = f(x), where y [the dependent variable] is based on the value of x [ the independent variable. So, to answer the question, a rational function, is one that involves a rational expression, such as y = 23x/2.
