i. let/(x) = 2x - 2 and g(x)-2x + 1. find 1(x) *9(x)
2x23x2+1
2. let g(a) = 2a +3 and h(a) - a - 1. find g(ayh(a)
3. let gon) - n - 2 and (n) = 3n+ 5. find g(n) + f(n)
4. let g(x) = x + 2 and h(x) = 2x + 4. find g(x) + h(x)
5. let f(x) = 7x* - 5x + 3 and g(x) = 2x + 4x - 6.
part a: find (x) + g(x)
part b: find f(x) - g(x)
part c: find g(x) - (x)

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
