Answer:
it is the first one
Step-by-step explanation:
Answer:
± sqrt(3)i = x
Step-by-step explanation:
0 = x^2 +3
Subtract 3 from each side
-3 =x^2 +3-3
-3 =x^2
Take the square root of each side
±sqrt(-3) = sqrt(x^2)
±sqrt(-3) = x
We can split sqrt(-3) into sqrt(3) sqrt(-1) and we know that the sqrt(-1) is i
± sqrt(3)sqrt(-1) = x
± sqrt(3)i = x
Answer:
(-4, 0)
Step-by-step explanation:
The x-intercept is when y = 0
Since y = 0 at x = -4, that is the row which reveals the x - intercept of the function.
