We have that
y = 2x + 8
for x=1-----------> y=2*1+8=10
for x=2-----------> y=2*2+8=12
for x=3-----------> y=2*3+8=14
.
.
.
the equation y = 2x + 8 ----------- > defines y as a function of x, because <span>for each x there is only one value of y</span>.
the answer is
yes, the equation y = 2x + 8 defines y as a function of x
The negative outside a function with no other transformations reflects the graph of the function over the x-axis.
<h3>How to Interpret Graph Transformations?</h3>
When we talk about reflection in transformation, we know that ;
Reflection over x-axis is defined as a reflection or flip over the x-axis where the x-axis is the line of reflection used.
The formula for this is: (x, y) → (x, −y) . To reflect an equation over the x-axis, simply multiply the output variable by negative one: y = f(x) → y = −f(x)
Thus, we can conclude that the negative outside a function with no other transformations reflects the graph of the function over the x-axis.

YES!
You know it like this:
if something (x)is 1/10 of a whole(y), then you need 10 of this for the whole (y).
So the whole is then:
y=x*10
if x=40:
y=40*10=400,,
so yes, 40 is 1/10 of 400.
