let f(x)=mx^2 + 2x + 5 and g(x)= 2x^2 - nx - 2. the functions are combined to form the new function h(x)= f(x)*g(x). points (1,-40) and (-1,24) satisfy the new function. determine f(x) and g(x)

Answer 1

use the two points they gave you.
f(1) = m+2+5 = m+7
g(1) = 2-n-2 = -n
h(1) = (m+7)(-n) = -40
Do the same for h(-1) and then solve for n and m. Check your final answer.
