QuestionFind $f(64)$ given the function $f(x)=9 \sqrt{x}$ . What is $f(64)=?$

Studdy Solution

STEP 1

Assumptions1. The function rule is $f(x)=9 \sqrt{x}$ . We need to find the value of $f(64)$

STEP 2

To find $f(64)$ , we need to substitute $x$ with $64$ in the function rule.
$f(64) =9 \sqrt{64}$

STEP 3

Now, calculate the square root of $64$ .
$\sqrt{64} =8$

STEP 4

Substitute the square root of $64$ back into the function.
$f(64) =9 \times8$

STEP 5

Finally, calculate the multiplication to find the value of $f(64)$ .
$f(64) =9 \times8 =72$ So, $f(64) =72$ .

QuestionFind f(64)f(64)f(64) given the function f(x)=9xf(x)=9 \sqrt{x}f(x)=9x​. What is f(64)=?f(64)=?f(64)=?

Studdy Solution

STEP 1

Assumptions1. The function rule is f(x)=9xf(x)=9 \sqrt{x}f(x)=9x​ . We need to find the value of f(64)f(64)f(64)

STEP 2

To find f(64)f(64)f(64), we need to substitute xxx with 646464 in the function rule.f(64)=964f(64) =9 \sqrt{64}f(64)=964​

STEP 3

Now, calculate the square root of 646464.64=8\sqrt{64} =864​=8

STEP 4

Substitute the square root of 646464 back into the function.f(64)=9×8f(64) =9 \times8f(64)=9×8

STEP 5

Finally, calculate the multiplication to find the value of f(64)f(64)f(64).f(64)=9×8=72f(64) =9 \times8 =72f(64)=9×8=72So, f(64)=72f(64) =72f(64)=72.
