Answer:

f(2) = 1

Step-by-step explanation:

f(x) where x = 2

we plug this into the function named f(x) and solve with the value plugged in

f(2) 1/2(2) = 1

Answer:

\large\boxed{f(2)=1;\ f^{-1}(1)=2;\ f^{-1}(f(2))=2}

Step-by-step explanation:

We have:

f(x)=\dfrac{1}{2}x and f^{-1}(x)=2x

f(2) → put x = 2 to the equation of a function f(x):

f(2)=\dfrac{1}{2}(2)=1

f⁻¹(1) → put x = 1 to the equation of a function f⁻¹(x):

f^{-1}(1)=2(1)=2

f⁻¹(f(2)) → put f(2) = 2 to the equation of a function f⁻¹(x):

f^{-1}(f(2))=f^{-1}(1)=2

Answer:

12 x^4 + 18 x^3 - 9 x^2 thus D is the correct answer.

Step-by-step explanation:

Expand the following:

3 x^2 (4 x^2 + 6 x - 3)

3 x^2 (4 x^2 + 6 x - 3) = 3 x^2 (4 x^2) + 3 x^2 (6 x) + 3 x^2 (-3):

3 4 x^2 x^2 + 3 6 x^2 x - 3 3 x^2

3 (-3) = -9:

3 4 x^2 x^2 + 3 6 x^2 x + -9 x^2

3 x^2×6 x = 3 x^(2 + 1)×6:

3 4 x^2 x^2 + 3×6 x^(2 + 1) - 9 x^2

2 + 1 = 3:

3 4 x^2 x^2 + 3 6 x^3 - 9 x^2

3×6 = 18:

3 4 x^2 x^2 + 18 x^3 - 9 x^2

3 x^2×4 x^2 = 3 x^4×4:

3×4 x^4 + 18 x^3 - 9 x^2

3×4 = 12:

Answer:  12 x^4 + 18 x^3 - 9 x^2

Solve for x give answer as radicals (roots)
skelet666 [1.2K]

Answer:

x = 15

Step-by-step explanation:

Use pythagorean theorem: a^{2} +b^{2} = c^{2}

8^{2} +x^{2} =17^{2} \\ 64 + x^{2} = 289 \\\\x^{2} = 289 - 64\\x^{2} = 225\\x = 15
