We are given a graph of a quadratic function y = f(x) .

We need to find the solution set of the given graph of a quadratic function .

<em>Note: Solution of a function the values of x-coordinates, where graph cut the x-axis.</em>

For the shown graph, we can see that parabola in the graph doesn't cut the x-axis at any point.

It cuts only y-axis.

Because solution of a graph is only the values of x-coordinates, where graph cut the x-axis. Therefore, there would not by any solution of the quadratic function y = f(x).

<h3>So, the correct option is 2nd option :∅.</h3>

Answer:

Option B. ∅

Step-by-step explanation:

If a quadratic function f(x) is in the form of f(x) = ax²+bx+c then the solution of the function is the value of x.

If we analyze the graph for f(x) ≤ 0 solution of the function is null because parabola doesn't intercept at x axis.

Therefore there is no solution for the graphed function f(x).

Option B is the answer.

4x−2y=14 y=12x−1 solve by substitution
Tatiana [17]

Answer:

x= -3/5

Step-by-step explanation:

4x-2y=14

y=12x-1

4x-2(12x-1)=14

4x-24x+2=14

4x-24x=12

-20x=12

×= -12/20

x= -3/5

56of the 90pets in the pet show are cats 4/5of the cats are calico cats. What fraction of the pets are calico cats?
meriva
To get the answer, we can divide 56 by 5 to find one fifth of the cats. Then, we can multiply this number to get four fifths of the cats. Then, we put this number over 90 since there is 90 pets in the entire show. Then, this answer ends up being about half all of the pets are calicos.

180 lb 12 oz - 79.3 kg = ___________ kg
Brrunno [24]

Answer:

180lb\ 12 oz - 79.3kg = 2.8kg

Step-by-step explanation:

Given

180\ lb 12\ oz - 79.3kg

Required

Solve

First, convert 180lb to kg

1lb \to 0.454kg

180lb \to 180 *0.454kg

180lb \to 81.7kg -- to 1dp

Next, convert 12oz to kg

1oz \to 0.03kg

12oz \to 12 * 0.03kg

12oz \to 0.4kg --- to 1 dp

So, the expression becomes:

180\ lb 12\ oz - 79.3kg

81.7kg + 0.4kg - 79.3kg

= 2.8kg

Hence:

180lb\ 12 oz - 79.3kg = 2.8kg

Given that cosine theta = -1/2 and theta is obtuse find sin4theta
igomit [66]

Answer:

0.8660

Step-by-step explanation:

cosine theta = -1/2

theta = cosinearctan(-0.5)

theta = 120

sine4theta = sine 4(120)

                   = sine480

                  = 0.8660
