Evaluate using direct substitution.

hii

f(n)=4n³+8n²-n-3

f(-2)=4(-2)³+8(-2)²-(-2)-3

=-32+32-1

f(-2)=-1

f(-2) = - 1

Step-by-step explanation:

f(n) = 4n^3 + 8n^2 - n - 3

f(-2) = 4(-2)^3 + 8(-2)^2 - (-2) - 3

f(-2) = 4(-8) + 8(4) + 2 - 3

f(-2) = -32+ 32 + 2 - 3

f(-2) = -1

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.
