What is the domain of the function y=3 in x graphed below?
2 answers:
Answer:
domain is x>0
Step-by-step explanation:
domain is the set of x values for which the function is defined
ln(negative value ) is undefined
So we take positive values for x because we have ln(x)
From the graph we can see that the given equation has a graph for x values greater than 0
the graph goes close to 0 but does not crosses y axis
So domain is x>0

Answer:
The equation of the line is 2 x - y + 5 = 0.
Step-by-step explanation:
Here the given points are A( 1, 7) & B( -3, - 1) -
Equation of a line whose points are given such that
( ) & (
)-
y - =
( x -
)
i.e. <em> y - 7= ( x- 1)</em>
<em> y - 7 = ( x -1)</em>
<em> y - 7 = 2 ( x - 1) </em>
<em> y - 7 = 2 x - 2</em>
<em> 2 x - y + 5 = 0</em>
Hence the equation of the required line whose passes trough the points ( 1, 7) & ( -3, -1) is 2 x - y + 5 = 0.
