Answer:
B) x = -5
Step-by-step explanation:
The zero of a graph is the inputted value in which the output is 0. Therefore, we must find the x-value that makes the y-value be 0. In the graph, we see that y = 0 at (-5, 0). The x-value of the coordinate (-5, 0) is -5. Therefore, the zero of the function in the graph is x = -5.
I hope this helps! :)
If y = f(x), then f⁻¹(y) = x.
We have f(x) = 2x + 2, so that f(x) = 4 when
2x + 2 = 4
2x = 2
x = 1
So we know f(1) = 4.
Then this means 1 = f⁻¹(4).

Answer:
<h3>6i</h3>
Step-by-step explanation:
Given the expression √-36
This can also be written as;
√36 = √36 * √-1
Since i² = -1
√-1 = i
Substitute into the resuting expression
√-36 = √36 * i
√-36 = 6i
Hence the required answer is 6i
