Answer: D
Step-by-step explanation:
A quadratic function has a degree of 2 so there will be two roots. The statement says the function does NOT CROSS THE X-AXIS so there are no real roots. That means both roots must be imaginary (complex).
We just multiply the scale to the dimensions
2 in to original is: 2×40= 80 cm
or do proportions:

=

=

=x
=80 cm=x the original dimension.
Same thing to the other side.
1.5×40=60 cm
or proportions again:

=


=y
60 cm=y
60 cm is the original dimension
80 cm times 60 cm ORIGINAL DIMENSION
