Answer:
c) -20x^2+14x+12
all real numbers
Step-by-step explanation:
So (fg)(x)=f(x)g(x)=(-4x-2)(5x-6).
Need find the expression in standard form we need to use foil:
First: (-4x)(5x)=-20x^2
Outer: (-4x)(-6)=24x
Inner: (-2)(5x)=-10x
Last: (-2)(-6)=12
--------------------------Add like terms:
-20x^2+14x+12
Polynomials have domain all real numbers.
There are no restrictions on what x can be. For every number you plug in, you will get a number back.
Reflection is the way of projecting a mirror figure to the other side of the axis of symmetry. When reflection is done, like what we can observe in the mirrors, the properties that can be observed are parallelism, colinearity and angle measure. Orientation is not preserved. Answer is C
Y=1/2 x +4
Slope = x coefficient = rise/run = 2/4=1/2
Y intercept= constant = 4
Answer:
(3.2, 0.6)
Step-by-step explanation:
means a translation of (x, y) → (x - 5.2, y + 1.4)
Suppose X has coordinates (a, b), after the translation is applied, X' has coordinates (a - 5.2, b + 1.4). X' is located at (-2, 2), therefore:
a - 5.2 = -2
a = -2 + 5.2
a = 3.2
b + 1.4 = 2
b = 2 - 1.4
b = 0.6
