Answer:
f(x) = 5x^2
Step-by-step explanation:
A vertical stretch is in the y direction
y = Cf(x) C > 1 stretches it in the y-direction
f(x) = 5x^2
Answer:
Yes
Step-by-step explanation:
A function correlates elements from a set one and only one element from a different set. Think of a train timetable: you can't have the same train in two points at a given time.
An easy way to solve the problem is to take a ruler (or the edge of a sheet of paper, as long as it's straight) and scan the graph parallel to the Y axis. As long as you don't touch the graph more than once, it's a function (zero points is ok!)
Answer:
in steps
Step-by-step explanation:
upper: a₁ = 50
t = a₁ - s
lower: a₁ = 1
z = a₁ + 5 n
a^2 = c^2 - b^2 = 64 - 4 =60
So a = the square root of 60.
