Answer:
y=5x
Step-by-step explanation:
From (2,10) you rise 25 in the y direction and run 5 in the x direction to get to the next known point (7,35).
Thus, the slope is y=25/5x AKA y=5x
Answer:
+ 6°F
Step-by-step explanation:
Change is (Final - Initial) [Change is subtract old value from new value]
(0°F -(-6°F)) = +6°F
Answer:
x intercepts -sqrt(5), + sqrt(5)
y intercept -5
Step-by-step explanation:
y = x^2 -5
to find the x intercept set y=0 and solve for x
0 = x^2-5
add 5 to each side
5 = x^2
take the square root of each side
+- sqrt(5) = sqrt(x^2)
x = +-sqrt(5) there are 2 x intercepts since it is a quadratic
to find the y intercept set x=0 and solve for y
y = 0-5
y = -5
Function g takes 4 as input and return 2 as output
f takes input 2 and returns output 4
from the graph
g(4)=2
f(2)=4
