Answer:
29
Step-by-step explanation:
Well "value" of 3x^2 - 7x + 9 when x = 4 is just x plugged into the expression
3 * 4^2 - 7 * 4 + 9
3 * 16 - 28 + 9
= 29
1)Alternate exterior
2) corresponding
3) alternate interior
4) non of these
Mark me brainliest
9-x/10=0
9-1/10x=0
90-x=0
-x=-90
x=90
f(- 9) = 2
f(- 9) is asking for the value of y when x = - 9
Locate x = - 9 on the x- axis
Then go vertically up to meet the graph at (- 9, 2 )
Thus when x = - 9, y = 2 , that is
