Answer:
The upper graph
Step-by-step explanation:
We have two quadratic function here
If we perform the function f(x) + g(x), which is nothing more than the sum of the two functions, we obtain a linear function, since the quadratic terms are eliminated by themselves
Answer:
the correct answer is 330.
Step-by-step explanation:
just plug the 7 into wherever there is an x in the equation
Answer:
The correct equation is fog = 4x^2 + 18x + 17
Step-by-step explanation:
In order to find fog, you need to put the g(x) equation in for x in the f(x) equation. Then simplify.
f(x) = x^2 + 3x - 1
fog = (2x + 3)^2 + 3(2x + 3) - 1
fog = (4x^2 + 12x + 9) + (6x + 9) - 1
fog = 4x^2 + 18x + 17
So y=-2+3 means y=3-2
y=1
so then subsitute 1 for y and solve
1=1/3x-1
add 1 to both sides
2=1/3x
multiply boht sides by 3
6=x
so x=6
y=1
