Given the parent function f(x) = 2x, which graph shows f(x) − 1?
1 answer:
Answer:
exponential function going through point 0, 0 and ending up on the right
Step-by-step explanation:
The given parent exponential function is .
This exponential function goes through (0,1) and ending up on the right.
The transformation shifts every point on the graph down by one unit.
Therefore the graph of will now go through (0,0) and end up on the right.
The correct choice is C

Answer:
5x - y = 27
Step-by-step explanation:
Slope is the direction of line and it is calculated as,
where (x₁, y₁) is any two points on the line.
Here, we have given that
Slope = 5 and (x₁, y₁) = (5, -2)
∴
⇒ 5(x - 5) = y + 2
⇒ 5x - 25 = y + 2
⇒ 5x - y = 27
Hence, the equation of a line is: 5x - y = 27
