HELP NEEDED,THANK YOU find all real zeros and complex of each function f(x)=x(4x-6)(x+1)(3x+5).SHOW WORK!!!
lisov135 [29]

Answer:

x=0, 3/2, -1, -5/3

Step-by-step explanation:

The x-axis interception points of x(4x-6)(x+1)(3x+5): (0, 0), (3/2, 0), (-1, 0), (-5/3, 0)

The y-axis interception points of x(4x-6)(x+1)(3x+5): (0,0)

So the answer is 0, 3/2, -1, and -5/3.

PLEASE HELP!!
miskamm [114]

Answer:  Choice A.   4 times

========================================================

Explanation:

We'll be using this formula

m = \frac{f(b)-f(a)}{b-a}

to compute the average rate of change (AROC) from x = a to x = b. Note how this is effectively the slope formula because y = f(x).

To start things off, we'll compute the AROC from x = 1 to x = 2.

m = \frac{g(b)-g(a)}{b-a}\\\\m = \frac{g(2)-g(1)}{2-1}\\\\m = \frac{5(2)^2-5(2)^1}{2-1}\\\\m = \frac{10}{1}\\\\m = 10\\\\

Do the same for the AROC from x = 3 to x = 4.

m = \frac{g(b)-g(a)}{b-a}\\\\m = \frac{g(4)-g(3)}{4-3}\\\\m = \frac{5(2)^4-5(2)^3}{4-3}\\\\m = \frac{40}{1}\\\\m = 40\\\\

The jump from m = 10 to m = 40 is "times 4", which is why choice A is the final answer.

Step-by-step explanation:

Distribute the three: 3(7x+4) will be changed to 21x+12-x

Next group like terms, -x+21x=20x

The new equation will be 20x+12
