8.2
3 does not add 1 to 2 so it's 8.2
Function: f(x) = x² -2x
Find y intercept:
y = 0² - 2(0)
y = 0
coordinates: (0, 0)
Vertex:
<u>-b/2a</u> = -(-2)/2(1) = 1
y coordinates = 1² - 2(1) = -1
vertex coordinates: (1, -1)
x intercept:
x² -2x = 0
x(x - 2) = 0
x = 0, 2
coordinates: (0, 0), (2, 0)
True statements:
option D
Answer:
Step-by-step explanation:
1/4 inch to 3/8 ft = x inches to 1 ft
(1/4) / (3/8) = x / 1
cross multiply because this is a proportion
3/8x = 1/4
x = 1/4 * 8/3
x = 8/12 which reduces to 2/3 inches <==

The significance of "b" in exponential function
An exponential function is represented as:
In the above equation, parameter "b" is the rate of the function
In other words, the constant multiplier of the function.
Take for instance;
By comparison:
Another instance is:
By comparison
<u>Other significance of parameter b are:</u>
If then b represents a growth factor
If the b represents the factor of decay
i.e. b is never 0
