Answer: Therefore, the geometric mean of 8 and 18 is 12. Therefore, the geometric mean of 8 and 18 is 12.
Step-by-step explanation:
F(x) = x²-4x-5, quadratic function,
Domain (the values if x) is all real numbers.
To find range we should draw a graph or to write an equation in vertex form.
f(x) = x²-4x+4-4-5
f(x) = (x-2)²-9
Point (-2,-9) is the vertex of the parabola, and it is a minimum because a parabola has positive sign in front of x², so it is looking up. Minimum value of y =-9
Range(the values of y) is [-9, ∞)
D. -48
Put it into your calculator exactly how it is shown up above and you will get the correct answer. Your calculator automatically knows the order of operations.

Answer:
The slope is 3 and the line is rising.
Step-by-step explanation:
To find the slope m of a line given two points (x₁, y₁) and (x₂,y₂) we can use the formula:
m = (y₂-y₁) / (x₂ - x₁)
In this problem we have the points (6,2) and (7,5), substituting these values in the formula we get:
m = (5 - 2) / (7 - 6) = 3/1 = 3
Therefore, the slope is 3.
Given that the slope is positive we can conclude that the line through the points rises.
