Question

can you help with this question please f(x)=−x+4 , determine the output values for each of the following input values. x =−2, x = −0.5, x=3

Answer 1

Answer:

f( -2 ) = 6,

f( -0.5) = 4.5

f(3) = 1

Explanation:

To evaluate the function at the given points, we put in the x values and evaluate.

For x = -2 we have

$f(-2)=-(-2)+4_{}$$f(-2)=2+4=6$$\boxed{f(-2)=6}$

For x = - 0. 5, we have

$f(-0.5)=-(-0.5)+4$$\boxed{f\mleft(-0.5\mright)=4.5.}$

For x = 3 we have

$f(3)=-3+4$$\boxed{f\mleft(3\mright)=1.}$

Hence, to summerise:

f( -2 ) = 6,

f( -0.5) = 4.5

f(3) = 1
