Answer:

your answer is correct for the reason you state

Step-by-step explanation:

A one-to-one function must pass the horizontal line test: no horizontal line intersects the graph at more than one place.

Here, the horizontal line y=3 intersects at x=1 and x=2, so the test fails.

Explain how to determine the zeros of f(x)= (x+3)(x-2)(x-6)

Deffense [45]

Answer:

The zeros of f(x) are -3, 2 , 6

Step-by-step explanation:

f(x) is a polynomial of degree 3.

If the polynomial is not factorized we will either factorize to find the zero or use trial and error method.

Since the f(x) in the question is in the factorized form. we will have to equate each factor to zero.

f(x) = (x+3)(x-2)(x-6)

x + 3 = 0 => x = -3

x - 2 = 0 => x = 2

x - 6 = 0 => x = 6

The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square fee

valentina_108 [34]

<h3>Therefore the area of remaining board =13.76 square feet</h3>

Step-by-step explanation:

Given , The length of side of the square is 8 feet.

Since a circle is inscribed in the square. Then the diameter of the circle is equal to the length of side of the square .

Therefore the diameter of the circle is = 8 feet.

Radius of the circle is(r) = $\frac{8}{2}$ feet = 4 feet

The area of the circle is= 3.14 r²

= 3.14 × 4² square feet

= 50.24 square feet

The area of the square is = side × side

= 8×6 square feet

=64 square feet

Therefore the area of remaining board = (64- 50.24)square feet

=13.76 square feet
