Step-by-step explanation:
To evaluate the function for
f(−3)
we need to substitute −3
for every occurrence of x
and then evaluate the results:
f(x)=x2+1
becomes:
f(−3)=−32+1
f(−3)=9+1
f(−3)=10
Answer:
substitute
−3
for every occurrence of x and then evaluate the results:
f(−3)=−32+1f(−3)=9+1
f(−3)=−32+1f(−3)=9+1 f(−3)=10
