GalinKa [24]

Answer:

5^2x^3y

Step-by-step explanation:

There are 2 factors of 5, so you have 5^2

There are 3 factors of x, so you have x^3

There is a single y, so you have y

Answer: 5^2x^3y

Consider the function f(x) = the quantity x squared minus x minus 12 all over the quantity x plus 3. Describe the graph of this
FromTheMoon [43]

Answer:

The graph of f(x) is discontinuous at x= -3. The x and y-intercepts or he function f(x) are (4,0) and (0,-4) respectively. The graph of the function is a straight line.

Step-by-step explanation:

The given function is

f(x)=\frac{x^2-x-12}{x+3}

f(x)=\frac{x^2-4x+3x-12}{x+3}

f(x)=\frac{x(x-4)+3(x-4)}{x+3}

f(x)=\frac{(x-4)(x+3)}{x+3}

Cancel out the common factor (x+3).

f(x)=x-4

It is a linear equation and it will give a straight line.

Put x=0, to find the y-intercept.

f(x)=0-4

f(x)=-4

Therefore the y-intercept is (0,-4).

Put x=0, to find the x-intercept.

0=x-4

4=x

Therefore the x-intercept is (4,0).

At x= -3 the value of denominator is 0, therefore the function is undefined for x= -3.

As x approaches toward x=-3 from left and right, the value of function approaches towards y=-7.

The function is discontinuous at x= -3.
