If a number is squared then you would multiply the number by itself

Ex: 9^2 = 81

Answer:

(f)x= x^2 +1    when x = 4

We are simply evaluating 17

Step-by-step explanation:

(f)x= x^2 +1x when x = 4

We are simply evaluating 20

The 1 in 1x represents 1 multiplied x and this represents

1*4

Together the last equation shows

x^2 + 1*4

=(4 x 4) + (1 x 4)

= 16 + 4

=20
