G(X) = 3x2+2x-1. Find G(-1).

G(x) = 3x2+2x-1. Find g(-1).

 

Answer:

g(-1) = 0

Step-by-step explanation:

g(x) = 3x² +2x - 1

What is g(-1)?

All we have to do is substitute -1 to the variable x

g(-1) = 3x² +2x - 1

= 3(-1)² + 2(-1) - 1

= 3(1) + (-2) - 1

= 3 - 3

g(-1) = 0

What are the other medical specializations that you know? List them and their areas of expertise below.   Some other medical specializations and types of a physician with their expertise: 1. Endocrinologist - Doctor of hormones. 2. Pathologist - Specialized in diseases 3. Obstetrics - Specialized in pregnancy and childbirth. 4. Oncologist - Specialized in cancers and tumors. 5. Orthopedist - Doctor of bones. 6. Family physician - Usually called the family doctor (self-explanatory). It depends on any family situation. 7. Psychiatrist - Give treatments and diagnosis of mental disability. Psychologist - An expert in the field of psychology. Doctor of human behavior. Investigating why IBM salespeople were so successful, researchers found that IBM set easy targets for their salespeople rather than targets that were difficult to reach and so most of their salespeople achieved their targets. IBM had hired psychologists to define optimum motivational goals for their sal...

Write True If The Statement Is True. Otherwise, Modify The Underlined Word(S) To Make It True. 2. Every Polynomial Equation Of Degree N Has N 2013 1 R

Write TRUE if the statement is true. Otherwise, modify the underlined word(s) to make it true. 2. Every polynomial equation of degree n has n – 1 real roots.   Polynomial Equation:         "Every polynomial equation of degree n has n - 1 real roots." This statement is false and in order to make it a true statement it should be... "every polynomial equation of degree n has at most n real roots" which is a consequence of the Fundamental Theorem of Algebra.     Definition:        A polynomial equation is any polynomial equated to zero . Examples: x - 2 = 0 x² + 2x + 5 = 0 5x + 1 = 0 x³  - 2x² - 4x + 8 = 0 x(x - 4) = 0 Explanation:   x - 2 = 0 the number of root(s) is just 1 since it is a polynomial of the first degree. x² + 2x + 5 = 0 the number of root(s) is 2 since it is a polynomial of the second degree. 5x + 1 = 0, there is only 1 root because it is a polynomial equation of the first degree. x³  - 2x² - 4x + 8 = 0 have 3 roots since its high...
