Answer:

b

Step-by-step explanation:

The graph crosses the x- axis at x = - 4 and x = 1, hence

x = - 4 and x = 1 are the zeros of the function, thus

(x + 4) and (x - 1) are the factors and

f(x) = a (x + 4)(x - 1)

The graph is a maximum therefore a = - 1

f(x) = - 1(x + 4)(x - 1) ← expand factors

f(x) = - 1(x² - x + 4x - 4)

    = - 1 (x² + 3x - 4)

   = - x² - 3x + 4 → b

(4x^3 - 5x^2 + 3) - (6x^3 + 2x^2 - x) Which of the following expressions is equivalent to the expression above?
weqwewe [10]

Answer:

c

Step-by-step explanation

    Factoring:  2x3-5x2+7x-6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  7x-6

Group 2:  2x3-5x2

so its c

Pull out from each group separately :

Group 1:   (7x-6) • (1)

Group 2:   (2x-5) • (x2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Help please!!!!!!!!!!!!!!!!
DedPeter [7]

Answer:

  x = 5

Step-by-step explanation:

The table and a graph of f(x) and g(x) are shown in the attachment. The solution is x=5. The table shows you f(5) = g(5) = 2, as does the graph.

It is generally convenient to make use of a graphing calculator or spreadsheet when repeated evaluation of a function is required.
