Answer:

Third option <u>(–2, 1, or 3)</u> is correct.

Step-by-step explanation:

The given: if f(x)=0

we need to find the points on  x, when  f(x)=0

Since, y=f(x)

then,

y=0

This means f(x) touches the x-axis

In provided graph, we can see at x= -2,1\; or 3 the y=f(x)=0

Hence, Third option <u>(–2, 1, or 3)</u> is correct.

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

if f(x)=0

if we let y=f(x)

then,

y=0,

So, that means when f(x) touches the x-axis,

According to the graph, we get that

At x= -2 f(x)=0

As xi negative in Second quadrant , and here we can see that f(x) touches the x-axis and intersect it.

At x=1, f(x)=0

At x=3, f(x)=0.

In above cases 'x' is positive, so, x lies in First quadrant, here too f(x) crosses the x-axis twice.

Hence, Third option is correct.

A plot of land has an area of 33.75 square feet. Jackson wants to put a 4-foot by 4-foot shed on the land. He can only do this i
Semenov [28]
The area of a trapezoid is
A = (1/2) h (b1 + b2)
where
h is the height
b1 is length of base 1
b2 is the length of base 2

We are given with the area and assuming that the trapezoid is isosceles, the length of base 1 is
b1 = 4 ft
If the height of the trapezoid is 4.5 feet, it ensures that the shed will fit inside the trapezoid patch of land. Therefore, the height of the trapezoid is 4.5 feet.
