Answer:
9
Step-by-step explanation:
Simply plug -3 in for x.
-2(-3)^2-7(-3)+6
(-3)^2=9
9*-2= -18
-7*-3=21
-18+21=3
3+6=9
Answer:
f(-3) = 9
Step-by-step explanation:
Here we have a quadratic function in x: and we want to know the value of this function when x = -3.
Substituting -3 for x in f(x) = -2x^2 - 7x + 6, we get f(-3) = -2(-3)^2 - 7(-3) + 6, which works out to f(-3) = -2(9) + 21 + 6, or
f(-3) = -18 + 27 = 9
Thus, f(-3) = 9
