a) The point (2, -7/5) is not a point on the graph?

b) The value of f(x) when x is 1 is -1/3 and the point on the graph is (1, -1/3)

c) The value of x for f(x) = 2 is 22 and the point on the graph is (22, 2)

d) The domain of x is all real values of x ≠ 10

e) The x intercept is -2

f) The y intercept is -1/5

<h3>What is a Function?</h3>

Function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output and not one input for two outputs.

Analysis:

a) To test if the point (2, -7/5) is a point on the graph, we put in x = 2 into the function,

f(2) = 2+2/2-10 = 4/-8 = -1/2 ≠ -7/5. Therefore (2, -7/5) is not a point on the graph.

b) if x = 1, f(1) = 1 +2 / 1-10 = 3/-9 = - 1/3

The point on the graph is (1, -1/3)

c) if f(x) = 2, then 2 = x+2/x-10

2(x-10) = x+2

2x -20 = x+2

2x-x = 2+20

x = 22, the point on the graph is (22, 2)

d) The domain of the function is such that the denominator would not be zero.

so if x - 10 ≠ 0

Then the values of x ≠ 10 are the domain of the function.

e) The x intercept of the graph is the point at which f(x) = 0

0 = x+2/x-10

x+2 = 0

x = -2. The x-intercept is -2.

f) the y-intercept is such that x = 0

0+2/0-10 = 2/-10 = -1/5

What is the factor of 5w + 20 show work

aniked [119]

5w + 20

Both terms have 5 in common, so you can factor out 5. Divide everything by 5, then put what you have in parentheses with the 5 outside of the parentheses.

5(w + 4) is your answer.

Two linear functions are displayed. Function One is represented by the graph:

GarryVolchara [31]

Answer:

Option A

Step-by-step explanation:

Function One is represented by the graph. We can see that the slope of the First Function is positive because the formula of slope is

$Slope=\frac{Change\ in\ y}{Change\ in\ x} \\\\$

And we can see that in the graph the change in y and change in x are both positive as the function is increasing because if we see the graph closely,

When x = 1 the value of y = 2 and when x = 2 the value of y = 4 and when x = 3 the value of y = 6 so the values are increasing of x and of y hence the slope is positive and the value of slope is 2.

Now the Second Function which is y = -4x here the slope is negative because the slope-intercept form of the equation is .

$y=mx+b$

and the second function is

$y=-4x$

if we compare both these equations we get the value of m = -4 where m is also called the slope. So the slope of the second function is negative.

Option B is incorrect because the slope of the first function is positive

Option C is incorrect because the slope of the second function is negative

Option D is incorrect because the slope of the first function is 2 and the slope of the second function is -4

That leaves us with Option A which is correct, where we can see that the slope of the first function is positive and the slope of the second function is negative
