Which of the following statements best describes the effect of replacing the graph of f(x) with the graph of f(x) - 5? The graph shifts 5 units up. The graph shifts 5 units down. The graph shifts 5 units left. The graph shifts 5 units right.
i think it is either d or a
a or d ??
|dw:1425081933994:dw| this h would tell u to shift right or left which is always suppose to be in parenthesis
k which is outside the parenthesis tell u to shift up or down so now what you think ?
a?
k is negative so.
if h is negative then shift right if h is positive shift to the left k is negative shift some units down k is positive shift some units negative
b?
yes right
Choose the equation below that represents the line passing through the point (1, -4) with a slope of one half. y - 4 = one half(x - 1) y + 4 = 2(x - 1) y + 4 = one half(x - 1) y - 4 = 2(x + 1)
c? @Nnesha
yep
Choose the equation below that represents the line passing through the point (2, -5) with a slope of -3. y = -3x - 13 y = -3x + 11 y = -3x + 13 y = -3x + 1
@Nnesha
slope intercept form is y = mx + b where m is slope which is always with x and b is y-intercept slope is -3 so replace m by -3 and use that order pair where (x , y ) and replace x and y by their values then solve for b
a or b i think it is b
@Nnesha
nope
c @Nnesha
how did you get c ?
i am guessing @Nnesha
it is getting really late and ia m so tired but o have to finish
yep i knew it
