1.) the quadratic function g(x) is the function f(x) stretched vertically by a factor of 5. let f(x)=4x^2+3. enter the equation g(x) in the box.

2.) the quadratic function g(x) is the function f(x) translated up 3 units. let f(x)=2x^2+1. what is the equation g(x)?

3.) the quadratic function g(x) is the function f(x) translated left 7 units. let f(x)= 2x^2-3. what is the equation g(x)?

20x^2+3 for number one. the answer to number two 2x^2+4. hoped that helped !!

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
