Question

F(х)=3x^2+5 f(x)=6 x=?

Answer 1

Ответ:

- √3/3; √3/3.

Объяснение:

f(x) = 3x² + 5

f(x) = 6, тогда

3x² + 5 = 6

3x² = 6 - 5

3х² = 1

х² = 1/3

х = ± √(1/3)

х = ± 1/√3

х = ± √3/3

Answer 2

To solve the equation f(x) = 6 and find the value of x, we'll set up the equation and solve for x.

Given the function f(x) = 3x^2 + 5, we need to find the value of x when f(x) = 6.

Setting up the equation:

3x^2 + 5 = 6

Subtracting 5 from both sides:

3x^2 = 1

Dividing both sides by 3:

x^2 = 1/3

Taking the square root of both sides (remembering to consider both the positive and negative square roots):

x = ±√(1/3)

So, the possible values of x are x = √(1/3) and x = -√(1/3).
