If f(x) = x² + 7, what is the value of f(4)?

dalvyx [7]

Value of f(4) is $f(4)= 23$ given $f(x)= x^2+7$

Step-by-step explanation:

We are given $f(x)= x^2+7$ and we need to find value of f(4)

Solving:

We will put x=4 and solve the given equation:

$f(x)= x^2+7$

$f(4)= (4)^2+7$

We know (4)^2=16

$f(4)= 16+7$

$f(4)= 23$

So, Value of f(4) is $f(4)= 23$ given $f(x)= x^2+7$

V = (1/3)Bh

where B represents the area of the base and h represents the height.

For your numbers, this is ...

V = (1/3)·(48 in^2)(14 in) = (16 in^2)(14 in) = 224 in^3
