Basically (g of f)x=(f(g(x)) so
g of f=f(g(x))=7(5x^2+4x-3)+5
distribute
f(g(x))=35x^2+28x-21+5=35x^2+28x-16
g of f=35x^2+28x-16
Answer:
f(x) = 0 on x= -1 and x = -2
Step-by-step explanation:
Given function is:
In order to find the value of x on which the function will have value zero we have to factorize the function and find zeroes of the function. The method used will be factorization of polynomial as the function is in polynomial form.
So,
To find the zeroes, putting the function = 0
Hence,
f(x) = 0 on x= -1 and x = -2
Answer:
-2 + 6!
Step-by-step explanation:
Since the last two are negatives back to back, you change them to positive to make the problem easier! Anytime the last two signs are back to back negatives, you can do that, but never change the first sign!
I hope this helps!!
