Answer:
The graph is not a function of x because x=0 intersects the graph at two points.
Step-by-step explanation:
The vertical line test is when you draw, well, a vertical line through the graph. the slope of a vertical line is undefined, and the formula written as x=_. So we can eliminate the choices with y=_.
We can clearly see that this graph isn't a function, so we can eliminate the answer choices that say that the graph is a function.
Just in case, draw a line at x=0, to check that it does indeed cross the graph in 2 places.
Answer:
- 66
Step-by-step explanation:
Evaluate g(- 4) then substitute the value obtained into f(x) , that is
g(- 4) = - 2(- 4)² = - 2 × 16 = - 32, then
f(- 32) = 2(- 32 - 1) = 2 × - 33 = - 66
Answer:
Amount of sales tax = $3.51
Step-by-step explanation:
$13.50 x 4 = $54
convert 6.5% to 0.065 ===> 6.5/100 = 0.065
$54 x 0.065 = $3.51
