Which of the following is a horizontal stretch of the parent function?

Mathematics

Answer:

The correct option is 3.

Step-by-step explanation:

The parent function is

f(x)=|x|

The horizontal stretch and compression is defined as

g(x)=|bx|

If 0<b<1, then it is horizontal stretch and if b>1, then it is horizontal compression.

Graph 1 passing thought the point (1,-1).

-1=|b(1)|

This statement is false for any value of b, because the value of modulus can not be negative.

Graph 2 passing thought the point (1,2).

2=|b(1)|

2=b

Since b>1, therefore this graph represent the horizontal compression.

Graph 3 passing thought the point (2,1).

1=|b(2)|

\frac{1}{2}=b

Since 0<b<1, therefore this graph represent the horizontal stretch.

Thus, the correct option is 3.

Find r if (r, 6) and (5, -4) are two points on a line with a slope of 5/7 (Hint: use the slope formula)
andreyandreev [35.5K]

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have

(r,\ 6),\ (5,\ -4)\\\\m=\dfrac{5}{7}

Substitute

\dfrac{-4-6}{5-r}=\dfrac{5}{7}\\\\\dfrac{-10}{5-r}=\dfrac{5}{7}\qquad|\text{cross multiply}\\\\5(5-r)=(-10)(7)\qquad|\text{use distributive property}\\\\25-5r=-70\qquad|-25\\\\-5r=-95\qquad|:(-5)\\\\\boxed{r=19}

What does the pair of equations y = 3, z = 7 represent? In other words, describe the set of points (x, y, z) such that y = 3 and
earnstyle [38]

Answer:

the pair of equations y = 3, z = 7 represent the intersection of two plans, The set of points is (0,3,7) and the line is parallel to x axis.

Step-by-step explanation:

Consider the provided equation.

y=3 represents a vertical plane which is in xy plane.

Z=7 represents a horizontal plane which is parallel to xy plane

The both planes are perpendicular to each other and intersect.

y=3 and z=7 is the intersection of two plans, where the value of x is zero y=3 and z=7.

The set of points is (0,3,7) and the line is parallel to x axis.
