The correct answer is 15:25
41
3 times 9 is 27
27+14=41
We have that
<span>f(x) = x/4 -3
g(x)= 4x</span>²<span>+2x-4
find (f+g)( x)
step 1
adding the two functions together to create a new function.
[x/4 -3]+[4x²+2x-4]
step 2
making everything have a common denominator of 4 we get:
[(x-12+16x²+8x-16)]/4
step3
combine like terms in numerator
(16x²+9x-28)/4-----------> 4x²+(9/4)x-7
the answer is </span>4x²+(9/4)x-7
<span>To find the domain, solve the inequality 4 - x > 0. x < 4. Thus, all numbers less than or equal to 4 represent thedomain for this function. When trying to find the domain and range from a graph, the domain is found by looking at the graph from left to right.</span>
