Functions f and g are defined as f(x) = 5x² - 10x + 7
where x > 1
g(x) = 7x - 6
Find fg(2)

247

Explanation:

When dealing with composite functions, we start with the right hand function first then apply our way to the left hand side.

1) First equate g(2)
2) Equate the function f of your answer you found in g(2)

1) 7(2) - 6
2) 14 - 6
3) 8

4) f(8) = 5(8)^2 - 10(8) + 7
5) f(8) = 320 - 80 + 7
6) f(8) = 247

Hope this helps, brainliest would be appreciated :)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
