Find the zeros in the function 3x2+ 6 = 0

Mathematics
1 answer:
sattari [20]3 years ago
5 0

Answer:

x = ± i \sqrt{2}

Step-by-step explanation:

Given

3x² + 6 = 0 ( subtract 6 from both sides )

3x² = - 6 ( divide both sides by 3 )

x² = - 2 ( take the square root of both sides )

x = ± \sqrt{-2}

  = ± \sqrt{2(-1)}

  = ± (\sqrt{2} × \sqrt{-1}) → \sqrt{-1} = i

  = ± i \sqrt{2}

Suppose f(x)=x^2 what is the graph of g(x)=f(2x)
Naddika [18.5K]

Answer:

Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):

g(x) = f(2x) = (2x)² = 4x²

Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.Step-by-step explanation:

Explain the relationship between the area and the radius of a circle.
Bess [88]

Area of a Circle: The area of a circle is the amount of space the circle takes up. To compute the area of a circle, we use the formula a=πr^2 where r is the radius of the circle.

Radius: The radius of a circle is the distance from the center of the circle to any point on the circle.
