Evaluate the function for the given value, easy 40

Answer: f(4)=256

step 1: rewrite equation

f(x)=4ˣ

step 2: substitute x

the equation tells us that x=4. let’s substitute that into everywhere we see x.

f(4)=4⁴

step 3: solve

exponents mean that you will multiply the number by itself that many times. for example in our equation 4⁴ means to multiply 4 by itself 4 times (4•4•4•4). let’s do this now.

f(4)=256
