Answer:
y=2x-9
Step-by-step explanation:
The slope is 2 and the y-intercept is -9
Answer:
y = 2x - 9
Step-by-step explanation:
Y2 - Y1/X2 - X1
7 - 1/8 - 5
6/3
= 2
y = 2x + b
1 = 2(5) + b
1 = 10 + b
-9 = b
y = 2x - 9
we have
Equate the expression to zero
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
Square root both sides
therefore
the answer is
Answer:
Its (4x+3)(x+2) 100%
Step-by-step explanation:
d(x) = –9
m(x) = –7x
p(x) = |x|
On the attached diagram you can see all graphs of functions b(x), d(x), m(x) and p(x).
Finding the inverse of a function f(x):
1. First, replace f(x) with y. This is done to make the rest of the process easier.
2. Replace every x with a y and replace every y with an x.
3. Solve the equation from Step 2 for y. This is the step where mistakes are most often made so be careful with this step.
4. Replace y with In other words, you’ve managed to find the inverse.
5. Remember: the domain of f is the range of and the range of f is the domain of .
Using this algorithm, you can find the inverse only in case C:
for m(x)=-7x:
1. y=-7x.
2. x=-7y.
3. y=-x/7.
4. .
5. The domain and the range of m(x) are all real numbers as well as the domain and the range of
Functions b(x) and p(x) are not one-to-one functions (see attached diagram), then you can't find an inverse function. Function d(x) doesn't include x, then you can't also find an inverse function.
