Answer:
la forma por el vector -1 5
Step-by-step explanation:
To find the inverse of this function, we first need to replace f(x) with y.
y = 2x^2 + 3
Now, we swap x and y
x = 2y^2 + 3
Now, we solve for y.
-3
x - 3 = 2y^2
Sqrt both sides.
√(x - 3) = 2y
Divide by 2
√(x - 3)/2 = y
Replace y with f^-1(x)
√(x - 3)/2 = f^-1(x)
Just realized you were asking for f(-1), not f^-1(x)
Feels bad.
f(-1) = 2(-1^2 + 3)
f(-1) = 2(-1^5)
f(-1) = 2(-1)
<u>f(-1) = -2</u>
I'm leaving the original answer in case you also need the inverse function. :)
2x - 3y < 12
-3y < -2x + 12...change the inequality sign because ur dividing by a negative number
y > 2/3x - 4
u have a slope of 2/3.....u have a y intercept of -4 or (0,-4)
to find the x int, sub in 0 for y and solve for x....disregard the inequality sign ....
y = 2/3x - 4
0 = 2/3x - 4
-2/3x = -4
x = -4 / (-2/3)
x = -4 * -3/2
x = 12/6
x = 2......and ur x int is 2 or (2,0)
so go ahead and plot ur intercepts (0,-4) and (2,0)....so start at (0,-4)...and since u have a slope of 2/3......go up 2 spaces and to the right 3 spaces...plot that point....then up 2 and to the right 3...plot that point...keep doing this and u will cross the x axis at (2,0)......now just draw a dashed line connecting ur plotted points
ur line will be a dashed line (because there is no equal sign in the problem)....ur shading will be above the line because it is greater then
Answer:
C. 53°
Step-by-step explanation:
<l + 96° = 149° <exterior angle of a triangle is equal to the sum of two opposite interior angles>
< l = 149° - 96°
<l = 53°
Hope it will help :)❤
