Answer:
Step-by-step explanation:
A. x is negative infinite to positive infinite
b. Y=3
c. Yes
reasoning
a. It’s asking what can x equal Be used domain is like another name for x and of you look on thw graph the arrow is crossing all the x points
B. It’s asking for y since range is another name for y and you see on the y axis, y is only interacts with three and no other point so it’s just y=3
C. It’s a function because it passes the vertical line tes!
The answer is D)6x^2 + 7x + 3

Answer:
x = -2/5 or 5
Step-by-step explanation:
We assume you want the values of x that make f(x) = 0. These are found using the zero product rule. That tells you a product is zero if and only if at least one factor is zero.
x -5 = 0 . . . . .assume the first factor is zero
x = 5 . . . . . . . add 5
__
5x +2 = 0 . . . assume the second factor is zero
5x = -2 . . . . . subtract 2
x = -2/5 . . . . divide by 5
__
smaller solution: x = -2/5
larger solution: x = 5
