Step-by-step explanation:
Given
f(x) = + 3x³ - 4x²
To find the zeros equate f(x) to zero, that is
+ 3x³ - 4x² = 0 ← factor out x² from each term
x²(x² + 3x - 4) = 0 ← factor the quadratic
x²(x + 4)(x - 1) = 0 ← in standard form
Equate each factor to zero and solve for x
x² = 0 ⇒ x = 0 with multiplicity 2
x + 4 = 0 ⇒ x = - 4
x - 1 = 0 ⇒ x = 1
zeros are x = - 4, x = 0, x = 1
First you need to find a common denominator, I'll use 72 so then it becomes:
52 32/72 + 8 63/72
Then I make them improper fractions so it becomes:
3776/72+639/72
Add them together and you have:
4415/72, this can be made into a mixed number:
61 23/72
Hope this helps :)
You'll actually need to graph for the first segment
but the second part can be solved with algebra
The equation of the line is y(x)=-x
if we test the co0ordinates we can find if the point lies on the line
(5,5)
y(x)=-x
Using the x co-ordinate
y(5)= -5
y=-5
Leaving us with (5,-5)
Because (5,-5) is not (5,5)
This is not a point on the line
The slope of the line is -1
