<h2>
Step-by-step explanation:</h2>
Since this is a logarithmic function, the domain is . But what is the domain of a function? The domain of a function is the set of inputs. This is so, because for any logarithmic function
, x must be greater than 0. So this function is continuous and has an x-intercept at 
, and y increases as x increases. Finally, its graph is shown below.
Answer:
y = -2x + 28
Step-by-step explanation:
Slope intercept form is-
y = mx + b
y = y coordinate
m = slope, the rise/run
x = x coordinate
b = the y-intercept, the place the line crosses the y-axis.
Now, fill in the formula with the proper information.
y = -2x + b You can use the point (10, 8) for the x and y coordinates to find b
8 = -2(10) + b Now solve for b
8 = -20 + b
<u>+20 +20 </u>
28 = b Now substitute 28 in for b
y = -2x + 28
Answer:
$3,250
Step-by-step explanation:
You take the initial fee of 250 then add 75x40
250x75(40)=$3250
Answer:
The correct option is A.
Step-by-step explanation:
The given equation is
Put x=0, in the given equation.
The y-intercept is (0,32).
Put y=0, to find the x-intercept.
Therefore the y-intercepts are (-4,0) and (8,0).
The vertex of a parabola 
is
Put x=2 in the given function.
The vertex is (2,36).
Therefore option A is correct.
