Step-by-step explanation:
y=-4x²
if <em><u>x=0</u></em> x=2
y=0 y=16
<em><u>x=</u></em><em><u>1</u></em> x=-2
y=4×1² <u>y=-16</u>
y=4
<em><u>x</u></em><em><u>=</u></em><em><u>-1</u></em>
y=-4
Using cross multiplication method,
x -12 -12x
x 2 2x
-24 -10x
Therefore,
=3(x-12)(x+2)
Answer:The normal resting heart rate for adults over the age of 10 years, including older adults, is between 60 and 100 beats per minute (bpm). Highly trained athletes may have a resting heart rate below 60 bpm, sometimes reaching 40 bpm. The resting heart rate can vary within this normal range.
Step-by-step explanation:
Answer:
Dilation
Step-by-step explanation:
Given
Main function: f(x)
Resulting function: 5f(x)
Required
Which transformation exists between both functions
The general explanation is that:
When a function f(x) is multiplied by a constant k, the resulting function g(x) is a dilation of f(x).
Mathematically, if the following relationship exists between f(x) and g(x)
g(x) = k.f(x)
Then g(x) is a dilation of f(x) and k is the constant of proportionality or dilation ratio
In this case:
g(x) = 5f(x)
So, the transformation that answers the question is dilation.
