Short Answer

Find the value of k0, k2, k−2, k2, ka+2, k−x, kx2 for the function kx=-x2−2x+3.

The value of function are

k0=3, k2=−5, k−2=3, k2=1−22, ka+2=−a2−6a−5, k−x=−x2+2x+3,kx2=−x4−2x2+3.

TABLE OF CONTENTS

Step 1. Evaluate k0,k2,k−2,k2 for the given function.

From the given function,

kx=−x2−2x+3 ....1

Evaluate the value of function at x=0,2,−2 gives,

role="math" localid="1644504817782" k0=−02−20+3 ....Substitute x=0 in 1 =3 k2=−22−22+3....Substitute x=2 in 1 =−5 k−2=−−22−2−2+3 ....Substitute x=−2 in 1 =3k2=−22−22+3 ....Substitute x=2 in 1 =1−22

Step 2. Evaluate ka+2,k−x,kx2 for the given function.

Similarly, evaluate the value of function (1) at x=a+2,−x,x2 gives,

role="math" localid="1644505036706" ka+2=−a+22−2a+2+3 ....Substitute x=a+2 in 1 =−a2−4a−4−2a−4+3 =−a2−6a−5 k−x=−−x2−2−x+3....Substitute x=−x in 1 =−x2+2x+3 kx2=−x22−2x2+3 ....Substitute x=x2 in 1 =−x4−2x2+3

Step 3. Description of steps.

From the obtained values,

k0=3,k2=−5,k−2=3,k2=1−22,ka+2=−a2−6a−5,k−x=−x2+2x+3,kx2=−x4−2x2+3.
