ERROR ANALYSIS Describe and correct the error in finding the x-intercept.
EastWind [94]

The x-intercept is -6

Step-by-step explanation:

In order to find the x-intercept, we put y = 0 and to find the y-intercept we put x = 0

In the given method, x is put equal to zero instead of y as x-intercept had to be found.

Given equation is:

-2x+3y=12

-2x + 3(0) = 12\\-2x +0 = 12\\-2x = 12

Dividing both sides by -2

\frac{-2x}{-2} = \frac{12}{-2}\\x = -6

The x-intercept is -6

Find the domain of f/g
san4es73 [151]

Answer:

C. All real numbers except 3/4

Step-by-step explanation:

We are given

f(x)=3x^2+x^4+2

g(x)=4x-3

Firstly, we will find f/g

\frac{f}{g}=\frac{3x^2+x^4+2}{4x-3}

Domain:

We know that domain is all possible values of x for which any function is defined

so, we know that denominator of any function can not be zero

so, firstly we set denominator =0

and then we can solve for x

4x-3=0

Add both sides by 3

4x-3+3=0+3

4x=3

x=\frac{3}{4}

so, this function is defined for all values of x except at

x=\frac{3}{4}

Domain will be

All real numbers except 3/4
