5. The mapping f: xax² + bx + c defined on the set of real numbers is such that f(0) = -4,f(1)-1 and/(-1)= -5. Find a, b and c.
Marrrta [24]

It looks like you're saying

f(x) = ax^2 + bx + c

and you're asked to find a,b,c given f(0)=-4, f(1)=-1, and f(-1)=-5.

Evaluate f at the three given points:

x=0 \implies f(0) = \boxed{c = -4}

x=1 \implies f(1) = -1 = a + b + c \implies a+b = 3

x=-1 \implies f(-1) = -5 = a - b + c \implies a - b = -1

(a+b) + (a-b) = 3 + (-1) \implies 2a = 2 \implies \boxed{a=2}

a-b = -1 \implies \boxed{b=3}

and the mapping is f(x) = 2x^2 + 3x - 4.
