14. Let R^2 have inner product defined by ((x1,x2), (y,, y2)) 4x1y1 +9x2y2 A. Determine the norm of (-1,2) in this space B. Dete
Vitek1552 [10]

The norm of a vector \vec x is equal to the square root of the inner product of \vec x with itself.

a. \|(-1,2)\|=\sqrt{\langle(-1,2),(-1,2)\rangle}=\sqrt{4(-1)^2+9(2)^2}=\sqrt{40}=2\sqrt{10}

b. \|(3,2)\|=\sqrt{\langle(3,2),(3,2)\rangle}=\sqrt{4(3)^2+9(2)^2}=\sqrt{72}=6\sqrt2

Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)​
Mkey [24]
<h2><u>Polynomial Function</u></h2>

<h3>Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)</h3>

To determine the answer, substitute the given value to the function and simplify.

  • h(x) = 3x² + 2 - 2x; h(-2)
  • h(-2) = 3(-2)² + 2 - 2(-2)
  • h(-2) = 3(4) + 2 + 4
  • h(-2) = 12 + 2 + 4
  • h(-2) = 14 + 4
  • h(-2) = 18

<u>Answer:</u>

  • <u>18</u> is the answer.
