The graph of the function f(x) = -(x + 3)(x - 1) is shown
below.
what is true about the domain and range of the function?
the domain is all real numbers less than or equal to 4,
and the range is all real numbers such that -3 sx s1.
the domain is all real numbers such that -35x31,
and the range is all real numbers less than or equal to
.
ahahah
4
the domain is all real numbers, and the range is all
real numbers less than or equal to 4.
the domain is all real numbers less than or equal to 4,
and the range is all real numbers.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
