Y intercept: when x = 0
Coordinate will be (0, y)
Look at the graph
Solution: y intercept: (0, 140)
Slope is the rate of change
(20,100) (0,140)
Slope formula: (y2-y1)/(x2-x1)
(140-100)/(0-20) = 40/-20 = -2
Solution: the slope is -2
Now use formula: f(x) = mx + b
m = slope, b = y intercept
Solution: function: f(x) = -2x + 140

If ƒ(x) = 2x² + 3, then which of the following represent ƒ(x + 1)?

Oliga [24]

This is a bit harder. I suggest getting the Domain and Range for the function of x.
If any of these answers have, an infinite domain and (3, infinite) range. That will be your answer.

Your answer is B.

f(x) = 2x²+3 has the same domain and range as x²+3
