Question

1. Find the domain and range of each function:
a) y = 1 + x2; b) y = y3 – x2​

Answer 1

Step-by-step explanation:

the values we put in x is our domain

and the values we get after solving the question for y is our range

for example if we put x=1 in (a) so 1 is our domain

and

y=1+x2

y=1+(1)2

y=1+1

y=2

we get answer 2 so 2 is our range

we can get many domain and range from this question
