Answer:
y=3/2x-1
Step-by-step explanation:
in slope intercept form, m means slope and b means y-intercept
Answer: Option B
2 is NOT in the domain of f ° g
Step-by-step explanation:
First we must perform the composition of both functions:
If and not
The domain of the composite function will be all real numbers for which the term that is inside the root is greater than zero. When x equals 2, the expression within the root is less than zero
The root of -7 does not exist in real numbers, therefore 2 does not belong to the domain of f ° g
The answer is Option B.
<em>Note. If </em>
So
And 2 belongs to the domain of the function
Answer:
Step-by-step explanation:
x^3 - 8x² - x + 8 =0
x^3 - 8x² - (x - 8 )=0
x²(x-8) - (x-8) = 0
(x-8)(x² -1) =0
x-8 = 0 or x² - 1 = 0
x-8=0 or (x-1)(x+1)=0
x=8 x=1 or x=-1
For an inverse relationship of the form
you can solve for k, the constant of variation (or proportionality), by multiply both sides of the function to get
. Substituting 5 for x and 10 for y, you see that k = 50.
