This is NOT a function. The reason why is because we are able to pass a single vertical line through more than one point on the cure. It fails the vertical line test.
For it to be a function, every input x must lead to exactly one output y
A. 4 (is the only factor for expression -48xyz -24xy +40)

Answer:
7.56 km²
Step-by-step explanation:
Given data:
Width of the fjord, w = 6.3 km
Retreated terminus of the glacier between may 2001 and June 2005, d = 7.5 km
thus, the length lost , y = 7.5 - 6.3 = 1.2 km
now, the area is given as:
A = Length × width
on substituting the values, we get
A = 1.2 × 6.3
or
A = 7.56 km²
Hence, the surface area lost by the glacier in the fjord is 7.56 km²
Should be the right answer ☺️
