Use the function f(x) to answer the questions.
frutty [35]

<u>Part A</u>

<u />-16x^2 + 60x+16=0\\\\4x^2 - 15x-4=0\\\\(4x+1)(x-4)=0\\\\x=-\frac{1}{4}, 4

<u>Part B</u>

The vertex of the graph will be a maximum because the leading coefficient is negative.

The x coordinate of the vertex is -\frac{60}{2(-16)}=\frac{15}{8}.

When x=15/8, f\left(\frac{15}{8} \right)=\frac{289}{4}.

So, the vertex has coordinates \left(\frac{15}{8}, \frac{289}{4} \right)

<u>Part C</u>

Plot the two x-intercepts and the vertex and then draw a curve in the shape of a parabola passing through them.

The graph is in the attached image.

Answer:

  (b)  {yly = -9, -3, 0, 5, 7}

Step-by-step explanation:

The range is the set of y-values in the ordered pairs. It is usually convenient to list a set in alphanumeric order.

The second values of the ordered pairs are 0, -3, -9, 5, 7. So, the range is ...

  y ∈ {-9, -3, 0, 5, 7} . . . . . matches the second choice

Solve the quadratic equation by completing the square.
ivolga24 [154]
X^2 - 10x + 15 = 0
x^2 - 10x = -15
x^2 - 10x + 25 = -15 + 25
(x - 5)^2 = 10 <====
x - 5 = (+-)sqrt 10
x = 5 (+-) sqrt 10

solutions are :
x = 5 + sqrt 10 and x = 5 - sqrt 10
