Need and answer asapwhich of the following shows the extraneous solution's to the logarithmic equation log_4(x)+log_4(x-3)=log_4(-7+21)x=- 7x=-3x=3 & x=-7x=7 & x=-3

the answer is d. (1.2, -4.7) on edgn

hope this !

a) 7x=7

step-by-step explanation:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
