The graph of the function, B(x), is shown below. Determine the following values for the function:

Softa [21]

Answer:

$B(-1) = 1\\\\B(3) = 0\\\\B(1) =2$

Step-by-step explanation:

By definition, a relation is a function if each input value has one and only one output value.

The input values are the x-values and the output values are the y-values.

Given:

$B(-1),B(3)$ and $B(1)$

We can identify that we need to find the output values of these input values:

$x=-1\\x=3\\x=1$

Observe in the graph attached that:

When $x=-1,\ y=1$

When $x=3,\ y=0$

When $x=1,\ y=2$

Therefore:

$B(-1) = 1\\\\B(3) = 0\\\\B(1) =2$

( Angle congruence and transformation ) Plz, if anyone can answer these I would appreciate it so much

Answer:

see explanation

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal

(a)

$\frac{AB}{DE}$ = $\frac{BC}{EF}$ , substitute values

$\frac{AB}{17.64}$ = $\frac{6.3}{13.23}$ ( cross- multiply )

13.23AB = 111.132 ( divide both sides by 13.23 )

AB = 8.4

(b)

$\frac{DF}{AC}$ = $\frac{EF}{BC}$ , substitute values

$\frac{DF}{4.1}$ = $\frac{13.23}{6.3}$ ( cross- multiply )

6.3DF = 54.243 ( divide both sides by 6.3 )

DF = 8.61
