Answer:
2
Step-by-step explanation
f(m) = m²-am+7
f(-1) = (-1)²-a(-1)+7 = 10
(-1)²-a(-1)+7 = 10
1+a+7 = 10
a+8 = 10
a = 10-8
a = 2

Answer:
2
Step-by-step explanation:
given
f(m)=m²-am+7
if m=-1 the value is 10
a=?
f(-1)→(-1)²-a(-1)+7=10
→1+1a+7=10
→1+a+7=10
→8+a=10
→a=10-8
→a=2
therefore the answer is is 2.
