Answer:
Step-by-step explanation:
B
The answer is (3,3) point to X move up four times than to the left 2 times
5/8 is a rational number because 5/8 as a percentage is 62.5. As long as the number doesn't go on forever without any patterns, it will be a rational number. If it does go on forever and doesn't have a pattern then it is an irrational number.
To solve the average rate of change, use the formula of the slope:
m = ( y2 - y1 ) / ( x2 - x1 )
but first we must solve the value of the function when x = 3
f(3) = - log ( 4 * 3 ) + 5
f (3) = 3.92
solve the function when x = 8
f(8) = - log ( 4 * 8) + 5
f(8) = 3.49
so the average rate of change
m = ( 3.49 - 3.92 ) / ( 8 - 3)
m = - 0.09
Subtract 3x from both sides:
-6y = -3x + 6
divide both sides by -6 to get y by itself:
y = 1/2x - 1
function notation is rewriting y as a function:
f(x) = 1/2x -1
