If the equation is then the domain is the set of all real numbers.
We can replace x with any real number and compute to get some real number output for y. There are no division by zero restrictions to worry about, or issues with taking a square root of a negative number (since this isn't really a square root function).
The cube root of a negative number is negative. For example, because (-4)^3 = (-4)*(-4)*(-4) = -64.
In interval notation, the domain would be written as to indicate the entire real number line.
Answer:
2
Step-by-step explanation:
The slope of the line is found by
m = (y2-y1)/(x2-x1)
= (-2-2)/(-4--2)
= -4/ (-4+2)
= -4/-2
= 2
Answer:
they are alternate interior angles and because we have parallel lines these two angles are equal
these angles are equal to 115°
Step-by-step explanation:
57x+1=56x+3
57x-56x=3-1
x=2
57x+1=57*2+1=114+1=115°
56x+3=56*2+3=112+3=115°
Take the derititve
f'(x)=3x^2+6x-24
set to zero
0=3(x^2+2x-8)
0=3(x-2)(x+4)
at x=2 and -4
those are where the min and max are
ok so
sign chart
to the lft of -4, the sign is positive
betweeen -4 and 2, the sign is negative
tothe right of 2 the sign is positive
max=sign changef from (+) to (-)
min=sign change from (-) to (+)
so max at x=-4 and min at x=2
find x=2, the value is -28
answer is C
2. 4th degree so quartic (qua, like quad or quadrilatal)
