True or false: f(x) is a function

Mathematics
1 answer:
EastWind [94]3 years ago
7 0

Answer:

It's true

Step-by-step explanation:

f(x) and g(x) are another name to use instead of y

A function is an equation which, for every x, has only one response for y. A function assigns each input of a given form to exactly one output.

Given the fuction h (x) = x^2 + 2x -3, find the value of h (2) - h (-4)
Anettt [7]

Answer:-

0

Step-by-step explanation:

h(x) = x^2 + 2x -3

x = 2

h(2) = 2^2 + 2(2) - 3

h(2) = 4 + 4 - 3

h(2) = 8-3

h(2) = 5

x = - 4

h(-4) = (-4)^2 + 2(-4) - 3

h(-4) = 16 - 8 - 3

h(-4) = 16 - 11

h(-4) = 5

========

h(2) - h(-4)

5 - 5

A rectangular yard has area 96 square feet. The width of the yard is 4 feet less than the length. Find the length. in feet, of t
Nikolay [14]

Answer:

24 ft

Step-by-step explanation:

To find the missing length, we start with the area. We know that we have an area of 96 square ft (although i dont know why someone would have such a big yard). We also know that the width of the yard is 4 ft. The next thing we do is divide. Since we multiply the length and width to find the area, we will divide the area by the width to find the missing length. 96/4= 24. Btw here is the weird yard someone has lol ( i made it to the best of my ability)
