Graph the linear function p(x)=-5x
1 answer:
The graph of linear function p(x)=-5x has Slope: −5 and y-intercept: (0,0)
Steps for graphing an equation using the slope and y-intercept:
Find the y-intercept = b of the equation y = mx + b.
Plot the y-intercept. The point will be (0, b).
Find the slope=m of the equation y = mx + b.
Make a single step, using the rise and run from the slope.
Connect those two points with your line.
Therefore , the graph is attached below of p(x)=-5x which has Slope: −5 and y-intercept: (0,0).

Answer:
No extraneous solution
Step-by-step explanation:
We have the logarithmic equation given by,
i.e.
i.e.
i.e.
i.e.
i.e.
i.e.
So, the solution of the given equation is x=4.
Now, as we domain of square root function is x > 0 and also, the domain of logarithmic function is .
Therefore, the domain of the given function is x > 0.
We know that the extraneous solution is the solution which does not belong to the domain.
But as x=4 belongs to the domain x > 0.
Thus, x = 4 is not an extraneous solution.
Hence, this equation does not have any extraneous solution.
