For this case we have the following equation:
-16 = 16x ^ 2
Clearing x we have:
-16 / 16 = x ^ 2
x ^ 2 = -1
x = +/- root (-1)
Rewriting:
x = +/- i
Therefore, the solutions are:
x1 = i
x2 = -i
Answer:
this equation has two solutions:
x1 = i
x2 = -i

The graph of the function f(x)=−4(x−3)2+9 will be a parabola opening in which direction?

sesenic [268]

Answer:

downwards

Step-by-step explanation:

the equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

• if a > 0 then parabola opens upwards

• if a < 0 then parabola opens downwards

for

f(x) = - 4(x - 3)² + 9 with a = - 4 < 0 , then

the parabola opens downwards
