Answer 1

( III ) f(x) = x^2

f(5) = 5^2

f(5) = 25

( I ) g(x) = -x^2 +7x +2

g(5) = -5^2 +7.5 +2

g(5) = -25 + 35 + 2

g(5) = 10 + 2

g(5) = 12

( IV ) h(x) = 3x^2 - 5x + 4

h(5) = 3.5^2 - 5.5 + 4

h(5) = 3.25 - 25 + 4

h(5) = 75 -25 +4

h(5) = 50+4

h(5) = 54

( II ) m(x) =2x^2- 13X

m(5) = 2.5^2 - 13.5

m(5) = 2.25 - 65

m(5) = 50 - 65

m(5) = -15
