Find f(2) if f(x)=(x+1)^2

9

Step-by-step explanation:

f(2), if f(x)=(x+1)^2

x=2

(2+1)^2

3^2=3x3

=9

f(x) = 9

Step-by-step explanation:

You know that x is equal to 2 because f(2) was originally f(x).

Now you know that x is and so you substitute x for 2

2 + 1 is 3 and 3 and 3 * 3 because the exponent is 2 is 9

okay so 15.15 *()5: +5/6

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
