How does a volcano form?

magma repeatedly comes up from beneath the surface and solidifies into igneous rock.

lava comes up from beneath the surface and solidifies into metamorphic rock.

magma at the surface hardens into metamorphic rock.

lava comes up from beneath the surface and hardens into igneous rock.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
