How do functions relate to graphs?

Mathematics

Gre4nikov [31]3 years ago

Functions relate to graphs because when you input a number in a function you get an exact answer for x and y, this is similar to how you can find where a line on a graph intersects and get your exact x and y answer.

Find the slope of the line going through the points (11,5) and (20,5)
Pani-rosa [81]
So remember the formula for working out the slope:

(y2 - y1) ÷ (x2 - x1)

We already know two points:

(11, 5) and (20, 5) (Remember points are like (x, y)


Therefore y2 = 5 and y1 = 5 and x2 = 20 and x1 = 11

Substitute these into the formula from the start:

(y2 - y1) ÷ (x2 - x1)
(5 - 5) ÷ (20 - 11)
0 ÷ 9

And we can determine the slope is equal to 0 as 0 ÷ 9 = 0

If f(x)=3x^2-2 and g(x)=4x+2 what is the value of f+g 2
Papessa [141]

Answer:

20

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = 3x² - 2 + 4x + 2 = 3x² + 4x

Substitute x = 2 into f(x) + g(x)

(f + g)(2) = 3(2)² + 4(2) = (3 × 4) + 8 = 12 + 8 = 20

Gnom [1K]

Answer: First Choice. 5²*x

Step-by-step explanation:

<u>Definition:</u>

When a number is squared in math, it means it's been multiplied by itself. There would be a (2) signifier as a subscript on the number.

Times in mathematics stands for multiplied by.

<u>Solve:</u>

" Five Squared Times Four"

Five = 5

Squared = ²

Times = ×

Four = 4

Finally, combined together will be:

  • 5² · x

Hope this helps!! :)

please let me know if you have any questions
