Question

Evaluate the function below for x=2. F(x)=x^46x^3+3 A.55 B.67 C.59 D.47

Answer 1

Answer : 67

Evaluate the function below for x=2.

$F(x)=x^4+6x^3+3$

To evaluate the function for x=2, we plug in 2 for x  in f(x)

Replace all x by 2

$F(x)=x^4+6x^3+3$

$F(x)=(2)^4+6(2)^3+3$

2^4 = 2*2*2*2= 16

2^3 = 2*2*2 = 8

f(2)= 16 + 6(8) + 3

= 16 + 48 + 3= 67

So f(2) = 67

The value of f(x) when x=2 is 67
