Q + (-9) = 12
-9 + q = 12
-9 + 9 + q = 12 + 9
9 + 9 = 0
0 + q = 12 + 9
q = 12 + 9
12 + 9 = 21
q = 21
Hope this helps.

Lim
insens350 [35]

Answer:

Step-by-step explanation:

f(-9+h)= (-9+h)² = h²-18h+81

f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81

f(-9+h)-f(-9)=h²-18h

(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18

lim  (f(-9+h)-f(-9))/h = lim(h-18= - 18

h→0                             h→0
