Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts?
vesna_86 [32]
<h2>Hello!</h2>

The answer is:

C) They both have the same y-intercept.

<h2>Why?</h2>

In order to find the correct option, we need to find the equation of the function g(x), and then, compare its y-intercept with the y-intercept of the f(x) function.

So,

- Finding the equation of the g(x):

Calculating the slope of the function, using the first two points (-1,8) and (1,0), we have:

m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{0-8}{1-(-1)}=\frac{-8}{2}=-4

Now, calculating the value of "b" using the first point (-1,8)  and the slope of the function, we have:

y=mx+b

y=-x+b

8=-4(-1)+b

b=4

So, the equation of g(x) is:

y=-4x+4

- Comparing the y-intercepts of f(x) and g(x):

Finding the y-intercept of f(x),  by making "x" equal to 0, we have:

y=x+4\\\\y=4

We have that the function f(x) has its y-intercept at "y" equal to 4.

Finding the y-intercept of g(x), by making "x" equal to 0, we have:

y=-4x+4

y=-4*(0)+4

y=4

We have that the function g(x) has its y-intercept at "y" equal to 4.

Hence, we have that both functions have their y-intercepts at the same point, so, the correct option is:

C) They both have the same y-intercept.

Have a nice day!

Find the area of the figure pictured below.
Tomtit [17]

Answer:

64 square units

Step-by-step explanation:

Split the figure into 2 rectangles of dimensions:

4 × 10

8 × 3

And solve.

(4 × 10) + (8 × 3) = 40 + 24 = 64 square units

See the attached image for a model.
