Question 6 (5 points)Find and .g(x) = 5x

h(x) = –10×3 + 13×2 – 3x + 3

Question 6 options:= –50X4 + 65X3 – 15X2 + 15X

= –1250×4 + 325×3 – 15×2 + 3x

= 50X3 + 65X2 – 15X + 15

= –1250×3 + 325×2 – 15x + 3

= –50X3 + 65X2 – 15X + 15

= –1250×3 + 325×2 – 15x + 3

= –50X3 + 65X2 – 15X + 15

= –1250×3 + 325×2 – 15x + 15
