Answer

$f(x) =2x^{2}+x^{3}+2x^{4}+2x+3$

Work Step by Step

$f''(t)==4+6x+24x^{2}$ Using the antiderivatives table, $f'(t)=4x+3x^{2}+8x^{3}+C$ Using the antiderivatives table, $f(x) =2x^{2}+x^{3}+2x^{4}+Cx+D$ $\left\{\begin{array}{llll} f(0)=3 & \Rightarrow & D=3 & \\ f(1)=10 & \Rightarrow & & 2+1+2+C+3=10\\ & & & C=2 \end{array}\right\}$ $f(x) =2x^{2}+x^{3}+2x^{4}+2x+3$
