Roots are the same as zeros, and you find them by factoring and solving for y. This one is easiest if done by "taking roots" method. Let's move the 176 over to the other side and then divide both sides by 4 to get the x^2 alone. If we do that have we get x^2 = -44. But we know that we cannot take the square root of a negative number without accounting for it by using the imaginary "i". Since "i" is equal to -1, let's rewrite that [sqrt-44] as [sqrt(-1)(44)]. Now let's simplify the 44 by finding its perfect square hidden in there: [sqrt(-1)(4)(11)]. Now, because -1 = i^2, we can rewrite that as well like this:
[sqrt(i^2)(4)(11)]. Both the i^2 and the 4 are perfect squares so that's what we pull out, leaving the 11 inside for an answer of x = +/- 2i[sqrt(11)]

Thank you so much
Step-by-step explanation:
With graphs like this, when you have the lowest point, you follow these steps:
Step 1) Find the lowest point. The lowest point is (1,-4)
Step 2) Find the y coordinate of this lowest point. The y coordinate is y = -4
The range is the set of possible y output values of a function. The range in this case is the set of real numbers y such that

(y is greater than or equal to -4). Basically y can equal -4 or it can be larger than -4. It is not possible for y to be smaller than -4
