Answer:
x ≠ 3
Step-by-step explanation:
The denominator of ...
f(x) = (x+2)/(x -3)
is zero when x=3, so the function is not defined there. Values of x for which the function is not defined are not part of the domain.
The restriction is: x ≠ 3.
_____
Please note that parentheses are required around numerators and denominators when a rational function is written in plain text. When it is typeset:
the division bar serves as a grouping symbol. In plain text, we cannot tell where numerator and denominator begin and end unless some other grouping symbol (parentheses) is used.
Answer:
see the explanation
Step-by-step explanation:
we have
Find the inverse of A(x)
Let
y=A(x)
Exchange the variables x for y and y for x
Isolate the variable y
Let
------> function inverse of A(x)
<em>Explanation</em>
For x=1
Find the value of A(x)
The point (1,7) is a solution for A(x)
That means-----> The point (7,1) is a solution for the function inverse g(x)
Verify
For x=7
The point (7,1) is a solution for g(x)
therefore
A(x) and g(x) are inverses of each other if the point (x,y) is a solution of A(x) and the point (y,x) is a solution of g(x)
Answer:
The midpoint is (-3,22)
Step-by-step explanation:
Use the midpoint formula (x1+x2 /2, y1+y2 /2)
Answer:
Answer
Step-by-step explanation:
The answer is d because if you at 17 to 197 you'll get 203
Answer:
(x²+1)(x-3)
Step-by-step explanation:
Factorize x³ + x - 3x² -3
x³-3x²+x-3
Factorize
x²(x-3)+1(x-3)
= (x²+1)(x-3)
Hence the factorized form is (x²+1)(x-3)
