The answer is -4. The range is the y-value and when you say f(x) that is the same thing as y, so if f(x) = -4 that means y = -4 which means the range is -4.

Answer:

384 cm²

Step-by-step explanation:

Since it is a square pyramid, the total surface area of the pyramid is the area of its square base plus the area of its 4 triangular faces.

$\boxed{area \: of \: triangle = \frac{1}{2} \times base \times height }$

Area of a triangular face

= ½ ×12 ×10

= 60 cm²

$\boxed{area \: of \: square = side \times side}$

Base area of pyramid

= 12 ×12

= 144 cm²

∴ Surface area of pyramid

= 4(60) +144

= 240 +144

= 384 cm²
