How do I graph this. I need to find the solution
Sergio039 [100]
To graph y=-7x-3, you're going to make your first coordinate at (-3,0) b/c that is your y-intercept and you will continuously move down 7 and right one.

To graph y=4, you will simply make a horizontal line through the to coordinate (4,0).

Hope that helped.

I need help with this promblem it’s ALGEBRA 2!
AlekseyPX

Answer:

(f\circ h)(2)=2

Step-by-step explanation:

<u>Composite Function </u>

Given f(x) and h(x) real functions, the composite function named (f\circ h)(x) is defined as:

(f\circ h)(x)=f(h(x))

It can be found by substituting h into f.

We are given the functions:

f(x)=2x^2-9x+2

h(x)=x^2-4

It's required to find (f\circ h)(2)

As defined above:

(f\circ h)(x)=f(h(x))

Thus:

(f\circ h)(2)=f(h(2))

Find h(2):

h(2)=2^2-4=0

h(2)=0

Now:

(f\circ h)(2)=2(0)^2-9(0)+2

(f\circ h)(2)=2
