Which of the function below could possibly have created this graph ?

lina2011 [118]

ANSWER

$f(x) = - {x}^{4} + {x}^{3} + 3 {x}^{2}$

EXPLANATION

The given graph rises on the left and falls on the right.

This implies that the degree of the function is even.

Since the graph opens downward, the coefficient of the leading term must be negative.

The graph graph of the function also has 3 intercepts with one of them having an even multiplicity.

This means that the degree must be 4.

Therefore the last choice is correct.

What are the zeros for both functions

sammy [17]

Answer:

the zero of a function is the value of x which makes the final value zero

First Equation:

So let 25 - 2x equal to 0

25 - 2x = 0

x = 12.5

Second Equation:

Let 2x² - 11x - 6 equal to zero

2x² - 11x - 6 = 0

2x² - 12x + x - 6 = 0 (Splitting the middle term)

2x(x - 6) + 1(x - 6) = 0

(2x + 1) (x - 6) = 0

So we can transpose either one of the brackets below the zero

(2x + 1) = 0 or (x-6) = 0

x = -1/2 or x = 6
