Answer:
Step-by-step explanation:
we have the expression:
We need to multiply the two terms in the first parenthesis by the two terms in the second parenthesis:
we solve each term taking into account the law of signs
(-)(-)=+
and
(+)(-)=-
also for the first term we use that
thus we have:
it can be simplified a little more if we factor an r of the second and third term:
For finding the answer of such a question, we only multiply the function by the given value. so as for f(x)=34x2−1, The function g(x), a vertical stretch of f(x) by a factor of 8 is g(x) =8(34x2−1)
Answer: 8
Step-by-step explanation:
distributive property = -18 + 3r = 6
cross river = 3r = 6 + 18
add = 3x = 24
lastly, divide = 8
