Question

Select the correct answer from each drop-down menu.
Consider the given quadratic equations.

Equation A Equation B Equation C Equation D
y = 3x2 − 6x + 21 y = 3x2 − 6x + 18 y = 3(x − 1)2 + 18 y = 3(x − 1)2 + 21
Complete the following statement.
Equations ( B and C, A and C, B and D, A and ) are equivalent, and of those, equation (A, B, C, D) is in the form most useful for identifying the extreme value of the function it defines.

Answer 1

Answer:

equation A and C are equal from

for equation C

y =3(x-1)^3+18

=> y=3( x^2 - 2x + 1) + 18

=> y = 3x^2 - 6x + 3 + 18

=> y = 3x^2 - 6x + 21

so eq A and eq C is equal
