Let f(x) = 3x^2+5, g(x)=3x-4. Find the following value or expression
(F*g)(x)=

Answers

Answer:

(f οg )(x) = 27 x² -36 x + 53

Step-by-step explanation:

Explanation:-

Given the function f(x) = 3 x² +5 and g(x) = 3x-4

(f οg )(x) = f(g(x)

             = f(3x-4)

             = 3 ( 3x-4)² +5  ( ∵  f(x) = 3 x² +5)

            =  3 ( 9 x² - 2(3x)(4)+(4)²) +5

           = 3 ( 9 x² -12 x + 16) +5

          = 27 x² -36 x + 48 +5

         = 27 x² -36 x + 53

Final answer:-

(f οg )(x) = 27 x² -36 x + 53

What is the equation of the following line? Be sure to scroll down first to see
all answer options.
10
-10
(0,0)
(10,-2)
10
Rest of the options are
D.y=- 1/5x
E. Y=5x
F.y=x

Answers

Answer:

D. y=-1/5(x)

Step-by-step explanation:

To find the equation of a line, use the formula y=mx+b, where x and y represent your x and y coordinates, m is your slope and b is your y-intercept.

b is you y-intercept, this is where the line cuts the y-axis. We can see from the graph that the line cuts the y-axis at (0,0), so c=0.

Now we have y=mx

Sub in one of our points (10,-2):

-2=m10

m=-1/5

So our equation looks like this:

y=-1/5(x)
