I. For the following problems: A). State the Domain; B) Find f(-2); C). Find f(1).
f(x) = -2x^2 + 3x – 4
f(x) = sqrt of (4-3X) +2
f(x) = 2x-5 over 3x +9
f(x) = -2x^2 + 3x – 4
f(x) = sqrt of (4-3X) +2
f(x) = 2x-5 over 3x +9
-
for all polynomial functions like 1st one domain is all real numbers
f(-2) is u simply substitute -2 in the place of x everywhere in the function like f(-2)=sqrt of (4-3(2))+2
similarly f(1) substituting 1 in hte place of x
f(-2) is u simply substitute -2 in the place of x everywhere in the function like f(-2)=sqrt of (4-3(2))+2
similarly f(1) substituting 1 in hte place of x
