Question

Algebra

Answer 1

for the first one, find \(g(0)=4\times 0+2=2\) then \(f(2)=\frac{1}{2+2}=\frac{1}{4}\)

Answer 2

second one is similar, but start with \(f(0)=\frac{1}{0+2}=\frac{1}{2}\) then find \(g(\frac{1}{2})\)

Answer 3

we need \(g(3)\) which cannot be seen from the picture

Answer 4

i attached second.

Answer 5

it it clear what \(g(3)\) is from the graph?

Answer 6

you are looking for \(g(f(1))\) so first, from the graph, what is \(f(1)\)?

Answer 7

here we find \(f(1)\) by locating 1 on the x axis, going up to the graph and finding the y coordinate
we see it is 3

Answer 8

so \(f(1)=3\) now we need \(g(3)\)

Answer 9

so its 4

Answer 10

yes

Answer 11

\[A=\pi r^2\]so ir \(r=5t+4\) you have \[A=\pi(5t+4)^2\]

Answer 12

lots of choices here
one would be \[\frac{4}{x^2}, x+2\]

Answer 13

last one

Answer 14

G(x+h)=9-(x+h)^2
G(x)=9-x^2
