Answer:
C) [-4,0)
Step-by-step explanation:
Look at the endpoints. You have (-3,0) which isn't included in the function and you have (1,-4) which is included in the function.
We use interval notation when we are describing the subset of numbers in a function by using parentheses to show an endpoint is not included and brackets to show an endpoint is included.
In this case, since we are being asked to find the range of the function, that only pertains to y-coordinates.
Given that (1,-4) is included in the function, this means that y=-4 is included in the function. Therefore the answer's interval notation will start with a bracket to show it's included.
Given that (-3,0) isn't included in the function, this means that y=0 isn't included in the function. Therefore the answer's interval notation will end with a parenthesis to show it's not included.
Combining the two elements, we have an interval notation of [-4,0) which means C is the correct answer
The 'template' for a quadratic function is:
, where <em>a</em> is the vertical stretch/compression factor.
If the <em>a</em> in f(x) is 2/5, then vertically stretching the function is done by multiplying the function by 2, making:
Answer:
(-2,5)
Step-by-step explanation:
D must be the same height (y) as A so y= 5
D must have the same x as C so x = -2
so D = (-2,5)
Answer:
Step-by-step Solution:
<u>Subtract or add to obtain your answer.</u>
- b + (−1.9) = −3.7
- => b - 1.9 = -3.7
- => b = -3.7 + 1.9
- => b = -1.8
Hence, the value of b is -1.8
