Eric wants to get an output of 0. can he do this with each machine? if so, how? if not, why not?

Explanation

The way each machine works is given by the expression (function) inside it.

1)  Function A

To get an output of 0 with the function y = x² + 3, you must solve the equation x² + 3 = 0.

Since x² is zero or positive for any real number, x² + 3 will never be less than 3 (the minimum value of x² + 3 is 3). So, it is not possible to get an output of 0 with the first machine.

2) Function B

Solve

So, he can get an output of 0 by using x = 4.

e) none of the above because the measure of angle cba is 101°

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
