B and d i think i just did it in my head!
Answer: f(-9)
Step-by-step explanation:
A function is described in the form of f(x)
Therefore, if this is how a function is stated we have x as the input.
Here, the x is equal to -9
So now:
f(-9) after substitution.
Answer:
Step-by-step explanation:
Domain of a function is given by the set of x-values (Input values) on the graph.
Range of a function is given by the set of y-values (output values) on the graph.
From the graph attached,
Set of time will represent the "domain" and set of snowfall will represent the "range" of the function graphed.
a). Domain of the function: 0 ≤ x ≤ 5
b). Range of the function: 0 ≤ y ≤ 10
Answer:
(-7, 0) are the coordinates of the function.
Step-by-step explanation:
The given function is f(x) = (x²+3x-28)/(x+7).
We have to find the coordinates of hole of the given function.
To find the coordinates of the hole we will find the factors of the numerator first.
x² + 3x - 28 = x²+ 7x - 4x -28
= x(x + 7) - 4(x + 7)
= (x + 7)(x - 4)
Now we know that factor (x + 7) is common as denominator therefore these factors will get cancelled.
Therefore x + 7 = 0
Or x = -7
and for x = -7 the value of y = (x²+3x-28)/(x+7) = 0
Therefore the coordinates of the hole of the given function is (-7, 0).
Answer:
2000
Step-by-step explanation:
In the equation, there is 0.02 attached to the x. This means multiplication. TO get rid of the 0.02, you need to do the opposite of multiplication. That is division.
Divide both sides by 0.02.
