Question 16436: Can you please help me with these two questions?
1.Tell whether the equation determines y to be a function of x. Problem: y=3+7x^2
2. Find g(w) and g(w+1) Problem: g(x)=3x-5
Thanks

y=3+7x^2 ... this will be a function if there is a definite value of y existing for every value of x under consideration .it is so in this case and hence it is a function.
2. Find g(w) and g(w+1) Problem: g(x)=3x-5
given g(x) , to find g(w) , we have to substitute w in place of x in the given function = 3w-5
similarly by substituting w+1 in place of x we get
g(w+1) = 3(w+1)-5 = 3w+3-5 = 3w-2
