Question

Find the following given the function f(x)=

Answer 1

Basically first you have to check what the f(x) fits into what category.

The picture shows different equations based on what the f(x) is.

In this case, f(x) is 7. So first check is 7 greater than 5, YES. But check with the next one too. Is 7 less than or equal to 5, NOPE

So your equation your going to be substituting with is x squared-x

Little bit stuck still? Here:

What is 7 to the power of 2 is 7x7=49

Then, 49-7=42

42 is your answer. If this is for RSM ENTER ONLY 42 INTO THE PORTAL.

I'm a student too and had this question too.

Answer 2

The function f defined by the formula f(x) = 2x +1 can be expressed as: f(4) = 9; f(-5) = - 9, f(0) = 1,

The function of a function defines and explains the relationship between two different variables. From the given information, we are meant to replace x with the following given options and solve for the value of x.

f(4) = 2(4) + 1

f(4) = 8 + 1

f(4) = 9

f(-5) = 2(-5) + 1

f(-5) = -10 + 1

f(-5) = - 9

f(0) = 2(0) + 1

f(0) = 0 + 1

f(0) = 1
