Answer:
y = 2x-2 if x <= 2
y = 3 if x > 2
Step-by-step explanation:
y = mx + b
and closed dot means = to
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).
(X + 4)(x - 1)(x -6) = (x^2 - x + 4x -4)(x - 6)
(x^2 + 3x -4)(x - 6) = x^3 -6x^2 + 3x^2 - 18x - 4x + 24 = x^3 - 3x^2 - 22x + 24
It is the first one
