The function g is defined by g(x)=3x^2+6.

Find g(5y)

3*(5y)^2 + 6 = __?

I get 75y+6

g(x)=3x^2+7 find g(2a)

75y^2-1

To find g(5y), we need to substitute 5y into the expression for g(x). Let's go step by step:

1. Start with the function g(x) = 3x^2 + 6.
2. Replace "x" with "5y": g(5y) = 3(5y)^2 + 6.
3. Simplify the expression inside the parentheses: g(5y) = 3(25y^2) + 6.
4. Square the value "5y": g(5y) = 75y^2 + 6.

So, the value of g(5y) is 75y^2 + 6.
