Tell what the output value is for the function machine for the given values.

Question

x^2+x^2+1

a)5
b)9
c)-7
d)1/2
e)t

Answer 1

I suspect a typo. Why not just say 2x^2+1?

At any rate, assuming things are correct as written, for any input, just substitute it for all the x's and evaluate for the output.

input: -2, output (-2)^2+(-2)^2+1 = 4+4+1 = 9

Answer 2

the dunction machine is x2 and -1 and the output is 7 and -20
