A) identifique entre os gráficos abaixo aqueles que determinam funções crescentes

B) calcule o coeficiente angular de cada ula das retas dos gráficos abaixo. (Utilize a taxa de variação e/ou a tangente do ângulo indicado)

C) determine quais gráficos correspondem a funções decrescentes

D) escolha, dentre os gráficos abaixo aqueles que representam funções constantes

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

the answer will be b x² +x-1

step-by-step explanation:

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
