Which of the following functions has a rate of change that stays the same?

Question

A)y = x2 – 5x –14
B)y = 19x – 10
C)y = 5x
D)y = 0.03x2 + 11x + 1

This is my question @Reed

Answer 1

B and C
19 and 5

Answer 2

But, which one exactly @damon

Answer 3

There are two with constant slopes. B and C
If you think there is only one answer, you have a typo.

Answer 4

B)y = 19x – 10

C)y = 5^x NOT THIS. This is NOT 5 x as you wrote later.

Answer 5

So the answer is C not B right??

Answer 6

I don't think I typed it wrong but, if I did then I am sorry.

Which of the following functions has a rate of change that stays the same?

A)y = x^2 – 5x –14
B)y = 19x – 10
C)y = 5^x
D)y = 0.03x^2 + 11x + 1

Answer 7

Look, they are asking you which of these is a straight line with constant slope.
In other words which looks like

Y = m X + b

That is B
y = 19 x - 10

A, x^2 - 5 x - 14 is a QUADRATIC, parabola

C, y = 5^x
(NOT y = 5 x )
is exponential

D, y = .03 x^2 etc
is QUADRQATIC, parabola

Answer 8

You typed y = 5x, look up above.
I found it correct in one of your earlier postings.

Answer 9

Ok so I know that the answer is B, thanks for answering

Answer 10

You are welcome, but more importantly do you know how to tell a straight line from a parabola or an exponential now?

Answer 11

Oh ok then. I was trying to repost it but, I think I put the question incorrectly

Answer 12

Yeah now I do thanks to you.

Answer 13

Good :)

Answer 14
