Consider the polynomial function f(x)=3x²+8x-4. Find f(2).
Triss [41]

Answer:

The value of polynomial for x = 2 that is f(2)  will be 32  

Step-by-step explanation:

We have given polynomial f(x)=3x^2+8x+4

We have to find the value of f(2)

We have to find the value of polynomial for x = 2

So for finding this value we have to just put x = 2 in polynomial

So f(2) will be f(2)=3\times 2^2+8\times 2+4=32

So the value of polynomial for x = 2 will be 32

What is the average rate of change for this quadratic function for the interval
Nesterboy [21]

The average rate of change of the function at the interval is -8

<h3>How to determine the average rate of change?</h3>

The table that completes the question is added as an attachment


From the table, we have:

f(5) = -26

f(3) = -10

The average rate is then calculated as:

Rate = (f(5) - f(3))/(5 -3)

This gives

Rate = (-26 + 10)/(5 -3)

Evaluate

Rate = -8

Hence, the average rate of change of the function is -8

F(x)=2x and g(x)=2x+3,what is the value of f(g(-8))
jok3333 [9.3K]

Answer:

f(g(-8)) = -26

Step-by-step explanation:

Given:

f(x)=2x and g(x)=2x+3

Required:

f(g(-8))=?

Solution:

First we will find g(-8)

g(x) = 2x+3

g(-8)= 2(-8)+3

      = -16 + 3

      = -13.

so, g(-8) = -13

Now, for calculation f(g(-8)) we can put the value of g(-8) i.e, -13

so, f(x) = 2x

    f(-13)  = 2(-13)

             = -26

so, f(-13) = -26

and f(g(-8)) = -26
