Write an equation for the

Mathematics
1 answer:
Travka [436]2 years ago

Answer:

See below

Step-by-step explanation:

For the model function f(x)=a|x-h|+k, (h,k) is the vertex, and a is the horizontal growth or shrink factor.

We know that our vertex is (-1.5,0) from our graph, so we'll need to determine the value of a by using one of the points on the graph:

f(x)=a|x-h|+k\\\\f(x)=a|x-(-1.5)|+0\\\\f(x)=a|x+1.5|\\\\f(0)=a|0+1.5|\\\\3=a|1.5|\\\\3=1.5a\\\\2=a

Thus, our equation for the given graph is f(x)=2|x+1.5|.

The domain of a function is the set of all existing real x-values, thus, our domain for the given function is (-\infty,\infty), or all real x-values.

The range of a function is the set of all existing real y-values, thus, our range for the given function is [-1,\infty), or all real y-values starting with y=-1 which is included.

A rectangular picture frame has perimeter of 58 inches. The height of the frame is 18 inches. What is the width of the frame?
Stells [14]

Answer:

11 inches

Step-by-step explanation:

A rectangle's perimeter can be found using:

p=2l+2w

We know that the perimeter, p, is 58, and the length/height is 18. Therefore, we can substitute those values in

58=2(18)+2w

Multiply 2 and 18

58=36+2w

Since we want to find the width, we need to get w by itself. First, subtract 26 from both sides

58-36=36-36+2w

22=2w

Since w is being multiplied by 2, divide both sides by 2. This will cancel out the 2, and leave w by itself.

22/2=2w/2

11=w

So, the width is 11 inches

Suppose f(x)=x^3 find the graph of f(x+1)
Basile [38]
F(x+1) = (x + 1)^3
= 3x + 3
= 3(0) + 3
= 3


I think is 3

suppose the annual rate of inflation average 3.8% over the next 10 years. the present cost of oil change for tour car is $23.95.
Mariana [72]
If the annual rate in 10 years has the same quadralaterical value the answer would be 47.9 but we can make sure our answer is correct
what we know:

The cost changed in 10 years to 23.95

if the cost changed another 10 years it would be another 23.95, 23.95+23.95=47.9 Which is our answer pls mark brainliest
