If f (x) = 3x^2 - 8x + 4 and g(x) = 4x^2 - 7x + 3 , then find f(x) + g(x)

If f (x) = 3x^2 - 8x + 4 and g(x) = 4x^2 - 7x + 3 , then f(x) + g(x) is

Solution:

Given that f(x) = 3x^2 - 8x + 4 and g(x) = 4x^2 - 7x + 3

To find: f(x) + g(x)

We can add or subtract two functions to create a new function. Just like we can add and subtract numbers, we can add and subtract functions.

f(x) + g(x) can be found by adding f(x) and g(x)

Combing like terms,

Thus the required function f(x) + g(x) can be found

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!
