If f(x) = x ² +1 and g(x) =3x+ 1,find [f(4)] ²
guajiro [1.7K]

Answer:

289

Step-by-step explanation:

We don't need g at all for this.

We will need to know f(4) before continuing...

f(4) can be found by replacing x in f(x)=x^2+1 with 4:

f(4)=4^2+1

f(4)=16+1

f(4)=17

-------------------

Now let's find [f(4)]^2:

[f(4)]^2

[17]^2

17(17)
