Answer:
Step-by-step explanation:
A point reflected across the y-axis maintains its y-coordinate, but its x-coordinate switches signs. So, a positive x-coordinate becomes negative, and a negative x-coordinate becomes positive.
Let's take a few points from the original function, f(x). Remember, if we know the function, we can find the y-coordinate for any x-coordiante by simply plugging it into the function's equation.
Generally,
So:
Leading us to have the plot points (0,0), (1,2) and (2,4).
To reflect this across the y-axis for the g(x) equation, we just need to turn the x-coordinates negative, resulting in a set of (0,0), (-1,2), and (-2,4).
Since we know this is a linear function (because there are no exponents in the equation), we can calculate the slope of this new set of points by using just 2 of them. The slope will give us our equation, because since (0,0) is a point on our line, we know that the y-intercept is zero.
Answer:
Coefficient of Q is 36.
Step-by-step explanation:
The coefficient means the constant term with the variable
Here, we need to find the coefficient of Q
We have been given an expression:
The coefficient of Q is the simplified form of the constant terms given:
Multiply the terms to get the simplified form which is:
Hence, the coefficient of Q is 36.
Answer:
A
Step-by-step explanation:
Using the definition
n =
where n! = n(n - 1)(n - 2).... × 3 × 2 × 1
Then evaluating numerator and denominator
10
=
=
Cancel 7(6)(5)(4)(3)(2)(1) on numerator/ denominator, leaving
= =
= 120
-------------------------------------------------------------------------------------
6
=
=
Cancel 4(3)(2)(1) on numerator/ denominator, leaving
=
= 15
-------------------------------------------------------------------------------------
Dividing numerator by denominator gives
= 8 → A
