Question

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

a.11

b. 19

c. 16

d. 8

Answer 1

to find g(4), all you have to do is to plug in 4 for x.

\[\huge\color{blue}{ g(4)=\huge\color{red}{ 4 } ^2+3 =16+3=19}\]SO,
\[\huge\color{blue}{ g(4)=19}\]

Answer 2

thank you i get it

Answer 3

You welcome!

Answer 4

can you help me with another question

Answer 5

I can try.

Answer 6

@SolomonZelman how did u type in an equation in colour?

Answer 7

For the function f(x) = x + 7, what is the ordered pair for the point on the graph when x = 2b?

A. (2b, 2b + 7)

B. (2b, x + 7)

C. (x, x + 7)

D. (x, 2b + 7)

Answer 8

\huge\color{ blue }{ }
size color

for example;
\huge\color{ red }{ x }
in equation editor that would look like \[\huge\color{ red }{ x } \]

Answer 9

thanx :)

Answer 10

Think of f(x) as being y. Thus if x =2b we know that is the value for x. Now what is the value for y.
F(x) = x+7 or f(x) = 2b+7. Think of f(x) as being y. Answer would be A.
