Answer:

The inverse function of 3x - 4 is (x+4)/3. so a

Step-by-step explanation:

f(x) = 3x - 4

y = 3x - 4 replace f(x) with y

x = 3y - 4 replace x with y and y with x.

3y = x + 4 solve for y

y = (x+4)/3 replace y with f-1(x)

f-1(x) = (x+4)/3

The perimeter of a 5-sided figure is 45.56 meters. Two of the sides have the same length. The sum of the other three side length

balandron [24]

10.68 each for the 2 same length sides. The total of the 5 sides is 45.56 less the 3 sides which total 24.2 leaves 21.36 remaining for the 2 equal length sides. So divide 21.36 by 2 = 10.68
(45.56 - 24.2)/2 = 10.68

The degree of the function f(x) = -(x + 1)2(2x - 3)(x + 2)2 is<br> , and its y-intercept is

Serggg [28]

Answer:

Degree = 5

Y intercept = 12

Step-by-step explanation:

our function is given as

$f(x)=-(x+1)^2 \cdot (2x-3) \cdot (x+2)^2$

in the above polynomial our variable is x and it is being multiplied for 5 times. Hence the probable degree for the above polynomial is 5

In order to find the y intercept , we need to put x=0 in f(x) as y intercept is the point at which the function graphically meets y axis and where x = 0

Hence

$f(0)=-(0+1)^2 \cdot (2(0)-3) \cdot (0+2)^2$
