Evaluate the function at the indicated values. (If an answer is undefined, enter UNDEFINED.) f(x) = 8x + 9 f(1) = f(−2) = f 1 2

creativ13 [48]

Answer:

f(1)=17

f(-2)=-7

$f(\frac{1}{2})=13$

Step-by-step explanation:

We are given that a function $f(x)=8x+9$

We have to evaluate f(1),f(-2) and $f(\frac{1}{2})$

Substitute x=1 in the given function then we get

$f(1)=8(1)+9=17$

f(1)=17

Substitute x=-2 in the given function then we get

$f(-2)=8(-2)+9=-16+9=-7$

f(-2)=-7

Substitute $x=\frac{1}{2}$

Then we get

$f(\frac{1}{2})=8(\frac{1}{2})+9=4+9=13$

$f(\frac{1}{2})=13$

The equation of the graphed line is 2x – y = –6.<br><br><br> What is the x-intercept of the graph?

Bas_tet [7]

U can either look at ur graph...and where the line crosses the x axis is ur x intercept...which is (-3,0)

OR

take ur equation and sub in 0 for y, and solve for x, ur x intercept.
2x - y = -6
2x - 0 = -6
2x = -6
x = -6/2
x = -3.....so ur x intercept is (-3,0)
