No as it doesn’t go vertically through 1/3 on x axis
Answer:
f(-3)=-8
Step-by-step explanation:
plug -3 in as x
-4(-3+5)
12-20
-8
H = -0.25 I think don't really know, okay?
The correct question is
<span>What are the vertex and x-intercepts of the graph of the function given below?
y = x</span>²<span>-2x-35
step 1
convert the equation in the vertex form
y+35=x</span>²-2x
y+35=(x²-2x+1-1)
y+35+1=(x²-2x+1)
y+36=(x-1)²------> equation in the vertex form
the vertex is the point (1,-36)
the answer Part a) is
the vertex is the point (1,-36)
Part b) Find the x-intercepts
we know that
the x-intercepts is when y=0
so
y+36=(x-1)²
for y=0
(x-1)²=36
(+/-)(x-1)=√36-------> (+/-)(x-1)=6
(+)(x-1)=6------> x=6+1-----> x=7
(-)(x-1)=6-----> x=1-6-----> x=-5
the x-intercepts are the points
(7,0) and (-5,0)
the answer part b) is
the x-intercepts are the points (7,0) and (-5,0)
the total answer is the option
<span>A. Vertex: (1, -36); x-intercepts: (7, 0) and (-5, 0)</span>
Answer:
see explanation
Step-by-step explanation:
To find the intercepts, that is where the graph crosses the x and y axes.
• Let x = 0, in the equation for y-intercept
• Let y = 0, in the equation for x-intercept
x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept
y = 0 : 8x + 0 = - 9 ⇒ x = -
⇒ ( -
, 0) ← x- intercept
