Too many different questions in one help request posting.

Domain of ?
Only restriction is .


Evaluate 4x^2-3x+2 if x=-1?

Compute that!


Line containing (1,1) and (2,4)?
, and gives you . Just pick either point to find b.


, solve.
Use Zero Product Rule.
Either 4x+1 is zero or 2x-7 is zero.

1.
If , evaluate .



2.
State the domain of the function .
denominator cannot be equal to zero;so, the domain will be all except one that makes and that is
so, the domain is:
{ element : }
or, interval notation:
(,) U (,)

3.
Write the equation of the line that passes through the points
(, ) and (, ). Write your answer in slope-intercept form.
Solved by pluggable solver: Find the equation of line going through points
hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (1, 1) and (x2, y2) = (2, 4).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(3)x + (-2)

Your graph:




so, your equation is:
4.
Write the equation of the line with a slope of and y-intercept of . Write your answer in slope-intercept form.
Solved by pluggable solver: Find the equation of the line(with graph)---slope a nd y-intercept:given

Using the slope-intercept form,

where m=slope, b=y-intercept,
and, substituting the values m=2/3 and b=1,

And the general equation is,






5.
Solve the equation:
...this product will be equal to zero if one or both terms are equal to zero
