The true statement about the function f(x) = -x² - 4x + 5 is that:
- The range of the function is all real numbers less than or equal to 9.
<h3 /><h3>What is the domain and range for the function of y = f(x)?</h3>
The domain of a function is the set of given values of input for which the function is valid and true.
The range is the dependent variable of a given set of values for which the function is defined.
- The domain of the function: f(x) = -x² - 4x + 5 are all real number from -∞ to +∞
For a parabola ax² + bx + c with the vertex
- If a < 0, then the range is f(x) ≤
- If a > 0, then the range f(x) ≥
The vertex for an up-down facing parabola for a function y = ax² + bx + c is:
Thus,
- vertex = (-2, 9)
Range: f(x) ≤ 9
Therefore, we can conclude that the range of the function is all real numbers less than or equal to 9.

Answer:
7.5%
Step-by-step explanation:
86 - 80 / 80 = 0.075
so 7.5%
Answer:
option D
Step-by-step explanation:
from the question 10>4-3x
it simply means 10-4>-3x
=6>-3x
x>6/-3
=x>-2
the above statement means that x is greater than -2
Hello!
We have to find how fast the car goes a minute
To find this we can do 57/60 since the car goes 57 miles an hour and there are 60 minutes in an hour
This gives us 0.95 miles a minutes
