Question

How do I do this and what is the answer?

If g(x) = x2 + 3, find g(4).

A) 11
B) 19
C) 16
D) 8

Answer 1

g(x) = x^2 + 3, find g(4)
So, 4 = 4^2 + 3.
Can you simplify from there?

Answer 2

not really. could you do it for me @EllenJaz17 ?

Answer 3

g(4)=4^2+3=16+3=19

Answer 4

ok thanks!

Answer 5

No problem!

Answer 6

could you help me with a few more problems @EllenJaz17 ?

Answer 7

Sure!

Answer 8

Ok Thanks! This is the first one:

If g(x) = 2(x - 4), find the value of x if g(x) = 20.

A) 32
B) 12
C) 14
D) 10

Answer 9

20 = 2x-8
20+8=2x
28=2x
28/2=x
14=x
