Explain how to use a graph of the function f(x) to
find f(3).

Answers

Answer 1
Answer:

Answer:

See below.

Step-by-step explanation:

f(3) means the y-coordinate of the point that has x-coordinate 3.

To find f(3) using a graph of f(x).

Look up x = 3 on the x axis. If the function passes through that point on the x-axis, then f(3) is 0. If the function does not pass through that point, then go up or down till you intersect the function. Draw a horizontal segment left to the y-axis and read the point on the y-axis that the horizontal segment intersects. That is what f(3) is equal to.
Answer 2
Answer:

Answer:

Sample Response: For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.

If x = 2/9 and y = 3/7 work out the value of x + y

Answers

Answer:

(41)/(63)

Step-by-step explanation:

=> x+y

Putting x = (2)/(9) ; y = (3)/(7)

=> (2)/(9) +(3)/(7)

LCM = 63

This will make the expression

=> (14+27)/(63)

=> (41)/(63)

This is the required factorized form

Answer:

\boxed{\sf (41)/(63)}

Step-by-step explanation:

hi, it means that we have to compute

(2)/(9)+(3)/(7)=(7*2+3*9)/(7*9)=(14+27)/(7*9)=(41)/(63)

mike drove to a frineds house at the rage of 40 mph. he returned hoke by the dsne route at 45 mph the driving time for the round trip was four hours how long did it take mike to get home

Answers

Let the distance be x miles

Time = Distance / speed

Time taken by Mike to go to his friend's house = x / 40 hours

Time taken by him to return = x / 45 hours

Total time = x / 40 + x / 45 = 4 hours

= 9x + 8x = 1440 miles

17x = 1440

= x = 1440 ÷ 7

= x = 84.706

Time taken to return home = 84.706 /45= 1.882 hours .

Therefore , Mike took1.882hoursto reach home .

Jason has decided to sell one of his baseball cards. The card is valued at $51.00. The store is only offering Jason $29.00. How much less is Jason being offered for his card than what it is valued at?*

Answers

well, just take the difference, 51-29, and 22 is how much less his card it being valued at. Or you can do 29-55, which would be -22, showing the amount and that it's valued less.
