Rational function:
A rational function is any function which can be defined by a rational fraction,
that is an algebraic fraction such that both the numerator and the denominator are polynomials
Let's assume
numerator polynomial is p(x)
denominator polynomial is q(x)
so, we can write rational function as
now, we will check each options
option-A:
we know that
we always get hole from rational function only
For exp:
Here , hole is at x=3
so, this is TRUE
option-B:
rational functions can not have irrational numbers
because we have both numerator and denominators are polynomial
so, this is FALSE
option-C:
We can get slant asymptote from rational function
For exp:
Here , slant line is y=x-3
so, this is TRUE
option-D:
Rational functions can have axis of symmetry
so, this is TRUE
Answer: with what
Step-by-step explanation:
The equationi of a line that passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
find slope
slope between points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(2,-5) and (-1,1)
slope=(1-(-5))/(-1-2)=(1+5)/(-3)=6/(-3)=-2
a point is (-1,1)
y-1=-2(x-(-1))
y-1=-2(x+1)
slope intercept is solve for y
y-1=-2(x+1)
y-1=-2x-2
add 1
y=-2x-1
