A function with zeros -3 and 2 could be:

(x + 3)(x - 2)  or  x² + x - 6

Keep in mind that there are an unlimited number of functions that have these zeros, such as:

2(x + 3)(x - 2)  or  2x² + 2x - 12
(x + 3)(x - 2)(x + 5)  or  x³ + 6x² - x - 30

Generally, the function just has to include the factors (x + 3) and (x - 2) to have the zeros -3 and 2.

What re the solutions of the equation x^2 +4x+4 = 25?
Oliga [24]
Get everything on one side: x^{2} +4x-21=0.  Now we can factor to find the solutions.  What we ask ourselves here is "What 2 numbers will add to be +4 and multiply to be -21?"  +7 and -3 work because 7-3 = 4 and 7 * -3 = -21.  So our factors are (x+7)(x-3).  Our solutions, however, are found using the Zero Product Property.  If x + 7 = 0, then x = -7.  If x - 3 = 0, then x = 3.  So our solutions are x = -7 and x = 3.

What are the domain and range of x= -2?
nikdorinn [45]

Answer:

The range is all real numbers, because it's a vertical line, and the domain is -2 because it's a vertical line with -2 as it's only x.

A dog and a cat are 200 meters apart when they see each other. The dog can run at a speed of 30 m/sec, while the cat can run at
Rzqust [24]

Answer:

A dog and a cat are 200 meters apart when they see each other. The dog can run at a speed of 30 m/sec, while the cat can run at a speed of 24 m/sec. How soon will they meet if they simultaneously start running towards each other?

Let x =distance travelled by dog and 200-x be the distance travelled by cat. Inorder to meet, the sum of their travelled distances shall be equal to 200 meters as they are far apart by 200 meters.

Dog: Distance =Speed x time: x=30t

Cat: Distance = 200-x=24t

The sum of their distance travelled shall be 200 meters: 30t+ 24t= 200;54t=200;t=200/54=3.7secs

So they will meet after 3.7 seconds

To check: Distance travelled by dog:x=30(3.7)=111.11 meters

Distance travelled by cat: 24t=24(3.7)=88.89 meters

Therefore since they are travelling towards each other and their distance apart is 200 meters, after 3.7 seconds they will meet because dog travelled 111.11 meters and cat travelled 88.89 meters and they covered already 200 meters as the sum of 111.11+ 88.89=200 meters
