Solve f(2)=4(2)^3-13(2)^2+8(2)+9

$$f ( 2 ) = 4 ( 2 ) ^ { 3 } - 13 ( 2 ) ^ { 2 } + 8 ( 2 ) + 9$$

Evaluate

$$5$$

Solution Steps

Calculate 2 to the power of 3 and get 8.

$$4\times 8-13\times 2^{2}+8\times 2+9$$

Multiply 4 and 8 to get 32.

$$32-13\times 2^{2}+8\times 2+9$$

Calculate 2 to the power of 2 and get 4.

$$32-13\times 4+8\times 2+9$$

Multiply 13 and 4 to get 52.

$$32-52+8\times 2+9$$

Subtract 52 from 32 to get -20.

$$-20+8\times 2+9$$

Multiply 8 and 2 to get 16.

$$-20+16+9$$

Add -20 and 16 to get -4.

$$-4+9$$

Add -4 and 9 to get 5.

$$5$$

Factor

$$5$$
