Answer:

X=1,  X=3  and  X=-1

Step-by-step explanation:

Given the expression (X-1)(X-3)(X+1):

# To find the rational values of X, we equate the equation to zero:

(X-1)(X-3)(X+1)=0\\\\X-1=0 \\\therefore X=1 \ \ \ \ ...i\\\\X-3=0\\\therefore X=3 \ \ \ \ \ ....ii\\\\X+1=0\\\therefore X=-1 \ \ \ \ \  ...iii

Hence for the values of X=3,X=1 and  X=-1 the expression equal 0

Which graph best represents the function f(x) = 3(1.5)x?
jok3333 [9.3K]

Answer:

B). graph of increasing exponential function going through point (0, 3)

Step-by-step explanation:

Given function is f\left(x\right)=3\left(1.5\right)^x

Now we need to find about which of the given choices best describes the given function. Where given choices are:

A). graph of increasing exponential function going through point 0, 2

B). graph of increasing exponential function going through point 0, 3

C). graph of increasing exponential function going through point 0, 1

D). graph of increasing exponential function going through point 0, 4

plug x=0 into given function

f\left(x\right)=3\left(1.5\right)^x

f\left(0\right)=3\left(1.5\right)^0=3(1)=3

Hence graph passes through point (0,3).

growth factor 1.5 is greater than 1 so that means it is increasing function.

Hence correct choice is:

B). graph of increasing exponential function going through point (0, 3)
