When you multiply a function by -1 what is the effect on its graph?

Mathematics
1 answer:
vlada-n [284]3 years ago

Answer:

Step-by-step explanation:

Depends on what you mean by multiplying by - 1.  I assume you are not going to multiply the y or f(x) term by - 1.

If that is so, take an example. Suppose you have a graph that is y=x^2

That's a parabola that opens upwards and it has a line going through its focus which is a point on the +y axis.

When you multiply the right hand side by - 1, the graph you get will be y = - x^2.

That opens downward and the focus is on the - y axis.

That means that the effect of the graph is that it flips over the x axis, which I think is the third answer.

You have not added your options, so I will just solve and hope that my answer is in your choices.

For the first equation we have:
3x-1=7+2
3x = 7+2+2
3x = 10
x = 10/2

For the second equation we have:
<span>2x+1+4=3
</span>2x = 3-4-1
2x = -2
x = -1

Therefore, there isn't a solution that satisfies both equations. Based on this, this system of equations has no solution.

Bill reads 1/5 of a book on Monday he reads 2/3 of a book on Tuesday if he finish reading the book on Wednesday what fraction of
Evgen [1.6K]

total book =1

1/5 + 2/3 + wed = 1

get a common denominator of 15

1/5 * 3/3 + 2/3 * 5/5 + wed = 1 * 15/15

3/15 + 10/15 + wed = 15/15

combine like terms

13/15 + wed = 15/15

subtract 13/15 on each side

wed = 15/15-13/15

wed = 2/15

He read 2/15 of the book on Wednesday

Find the area of the following geometric figure
romanna [79]

The area of the triangle is 90 m²

Explanation:

Given that the base of the triangle is 15 m

The altitude of the triangle is 12 m

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

Area=\frac{1}{2}bh

where b is the base and h is the altitude

Thus, we have,

b=15 and h=12

Substituting the values in the above formula, we get,

Area=\frac{1}{2}(15)(12)

Multiplying the terms, we get,

Area=\frac{180}{2}

Dividing, we get,

Area=90 \ m^2

Therefore, the area of the triangle is 90 m²
