Halla la tasa de variación de cada funcion en el intervalo [-4,3] e indica si es positiva , negativa o nula A) f(x)=x2-2x+4 B) f(x)= -3x + 2 En rl ejercico A es x elevado al 2 o cuadrado

Step-by-step explanation:

Given a function , we called the rate of change to the number that represents the increase or decrease that the function experiences when increasing the independent variable from one value "" to another "".

The rate of change of between and can be calculated as follows:

For:

Let's find and , where:

So:

And for:

Let's find and , where:

So:

Translation:

Dada una función , llamábamos tasa de variación al número que representa el aumento o disminución que experimenta la función al aumentar la variable independiente de un valor "" a otro "".

La tasa de variación de entre y , puede ser calculada de la siguiente forma:

answer: need picture of problem

step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
