Question

I AM GOING TO SCREAM!! I HAVE LITERALLY DRAINED MY POINTS FOR SOMEONE TO ANSWER THIS QUESTION - answer both a and b plz, brainliest goes to the person with the right and most helpful answer.

QUESTION:
For all values of x,
f(x) = $x^{2}$+3 || g(x)=2x-1

a) Find fg(2)
b) Find gf(2)

Answer 1

Answer:

a) 12

b) 13

Step-by-step explanation:

f(x) = x^2 + 3

g(x) = 2x - 1

a) f(g(2)) = ?

g(2) = 2(2) - 1

= 4 - 1

= 3

f(g(2)) = f(3) = 3^2 + 3

= 9 + 3

= 12

b) g(f(2)) = ?

f(2) = 2^2 + 3

= 4 + 3

= 7

g(f(2)) = g(7) = 2(7) - 1

= 14 - 1

= 13
