Answer: y=2x+2
Step-by-step explanation:
slope-intercept form: y=ax+b
----------------------------------------
#1 Find the slope
- Use rise/run to find the slope: 8/4=2
- Use slope formula: (2-(-6))/(0-(-4))=8/4=2
#2 Find the y-intercept
- Given the point (2, 0) it is already the y-intercept which is 2
----------------------------------------
a=2
b=2
y=2x+2
Answer:
g(x) = f(3x) -15
Step-by-step explanation:
Let f(x) be the parent function.
If the function is to be compressed by a factor of 3 horizontally, we must obtain the value f(3) when x=1, for example. We can do that by using 3x as the argument of the function:
g(x) = f(3x)
If its graph is to be shifted downward by 15 units, every value produced by the function must have -15 added to it. That is, the shifted function is ...
g(x) = f(3x) - 15
_____
The attached graph shows an example function compressed horizontally and vertically shifted.
Answer:
x = 2.
Step-by-step explanation:
The corresponding sides are in the same ratio (because they are similar).
So 5x / 5 = 4 /x
5x^2 = 20
x^2 = 4
x = 2.
Answer:
-8
Step-by-step explanation:
put -2 in when ever you see x
so -(-2)-10
2-10
-8
