Determine whether each function is linear or quadratic. Identify the quadratic, linear, and constant terms. g(x)=-2 x²-3(x-2)
valentinak56 [21]

   The function g(x) is a quadratic function:

  • Its quadratic term is -2x²
  • Its linear term is - 3x
  • Its constant is 6

<h3>What are functions?</h3>

 Functions are algebraic expressions that have at least two variables, in order to make their visual representation through a graph and evaluate their behavior.

 This problem deals with linear or quadratic functions, and these differ in the degree of the exponent of the variable:

  1 : linear

  2 : quadratic

  The function:

g(x) = -2x² - 3(x- 2).

g(x) = -2x² - 3x + 6 , we have a quadratic function.

  • Its quadratic term is -2x²
  • Its linear term is - 3x
  • Its constant is 6

Martha has driven about 2/3 the distance she needs to go to reach her aunt's house. Her brother Jackson is making the same trip
Harman [31]
The answer is A. Martha has a shorter distance left to get to the aunt’s house than Jackson since 2/3 is .667 or 67%. Therefore this statement is false

So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles
