Evaluate the function for the given value.

f(-3) if f(x) = 4x^2 + 7

Step-by-step explanation:

f(x) = 4x² + 7

To find f(-3) substitute the value of x that's - 3 into f (x) that's replace every x in f (x) by - 3

We have

f(-3) = 4(-3)² + 7

= 4(9) + 7

= 36 + 7

We have the final answer as

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!
