Answer:
f(0)=4
Step-by-step explanation:
f(0)=4*9^0=4*1=4
I think that it is geometry.
4(x+7)=8x-20
4x+28=8x-20
28=4x-20
48=4x
x=12
Answer:
2y-4x
Step-by-step explanation:
Find where the equation is undefined ( when the denominator is equal to 0.
Since they say x = 5, replace x in the equation see which ones equal o:
5-5 = 0
So we know the denominator has to be (x-5), this now narrows it down to the first two answers.
To find the horizontal asymptote, we need to look at an equation for a rational function: R(x) = ax^n / bx^m, where n is the degree of the numerator and m is the degree of the denominator.
In the equations given neither the numerator or denominators have an exponent ( neither are raised to a power)
so the degrees would be equal.
Since they are equal the horizontal asymptote is the y-intercept, which is given as -2.
This makes the first choice the correct answer.
