Suppose you have:
u = 2f + 14
f = 4x - 4x²
What is u in terms of x?

put the whole thing after f = in the first equation

so

x^2 means x squared

so

u = 2 (4x - 4x^2) + 14

so

u = 8x - 8x^2 + 14

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
