Answer:
∞, or (-∞, ∞)
Step-by-step explanation:
Basically we're asking when x is undefined. We can tell this a variety of different ways, but the easiest is knowing the rule that a normal function (one that isn't square rooted, taken the log of, or has an x value in a denominator) such as this one will always have a domain that goes to infinity.
F(-1)= 4*7(-1) = 4*-7 = -28
F(2)= 4*7(2) = 4*14 = 56
Answer:
2
Step-by-step explanation:
To find slope just compare two points on a graph then put them into a fraction like so y₁ - y₂/x₁ - x₂
Answer:
2nd choice OC.y=-2x+3
Step-by-step explanation:
The equation for the slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. With these two numbers both given to us, we can just plug them in and get y=-2x+3.
Hope this helps you
Answer:
4
Step-by-step explanation:
Basically the y - intercept is where the graph intercepts with the y axis. The y axis is the vertical line in the middle of the graph. As you can see, the the graph and the y axis intersect at about 4.
