Answer:
289
Step-by-step explanation:
We don't need [tex]g[/tex] at all for this.
We will need to know [tex]f(4)[/tex] before continuing...
[tex]f(4)[/tex] can be found by replacing [tex]x[/tex] in [tex]f(x)=x^2+1[/tex] with [tex]4[/tex]:
[tex]f(4)=4^2+1[/tex]
[tex]f(4)=16+1[/tex]
[tex]f(4)=17[/tex]
-------------------
Now let's find [tex][f(4)]^2[/tex]:
[tex][f(4)]^2[/tex]
[tex][17]^2[/tex]
[tex]17(17)[/tex]
[tex]289[/tex]
Answer:
289
Step-by-step explanation:
Evaluate f(4) by substituting x = 4 into f(x), that is
f(4) = 4² + 1 = 16 + 1 = 17, then
[f(4) ]² = 17² = 289
